Tokyo 2020 Qualifying — Weightlifting

Filed under: General,weightlifting — Tags: , , , — Michael @ 14:25

I base the following summary on my own reading of IWF’s Qualification System – Games of the XXXII Olympiad Tokyo 2020. This summary is NOT an official publication of any sanctioning body; it is my own interpretation. This summary does not address “Host Country” or “Tripartite Commission” spots.

Qualifying sub-periods

  • Period 1: Six months from November 2018 through April 2019
  • Period 2: Six months from May 2019 through October 2019
  • Period 3: Six months from November 2019 through April 2020

Athlete Required Participation

  • Participate in at least six events (at least two of these in an Olympic weight class).
  • Participate in at least one event in each six-month period above.
  • At least one event must be Gold Level, and a second must be either Gold or Silver Level.

Event Levels

  • Gold Level: IWF World Championships, IWF Junior World Championships, Continental Championships, Junior Continental Championships.
  • Silver Level: Existing IWF Events: Multi-Sport Games, Championships.
  • Bronze Level: other International competitions, Championships, Cups, etc.

Qualifying Pathways

  • Be one of the eight highest-ranked lifters to qualify for an Olympic weight class.
  • Or be the highest-ranked lifter from one of the five Continental federations.
    • Africa, Asia, Europe, Oceania, Pan America
  • See “IWF Absolute Ranking” below.


  • Maximum of one lifter per country in any weight class.
  • Maximum of four lifters per gender from any country. Except…
    • Maximum of two lifters per gender from any country that has had 10 to 19 IWF doping violations since 2008.
    • Maximum of one lifter per gender from any country that has had 20 or more IWF doping violations since 2008.
  • Each NOC chooses its team from among its qualified athletes.


Due to the limits above (and other possible causes, including redundant qualifications), National Olympic Committees (NOCs) of some of the “Top 8” and “Top Continental” qualifiers may not get to use all invitations. In these cases, IWF reallocates as follows:

  • Top 8 — Next-highest ranked athlete whose NOC is not yet qualified in the class.
  • Continental — Next-highest ranked athlete from that same continent whose NOC is not yet qualified in the class.

IWF Absolute Ranking

Each athlete’s final Absolute Ranking Points total, determined at the end of the qualifying period (April 30, 2020), is the sum of the following four scores:

  • the lifter’s best adjusted Robi score in each of the three time periods and…
  • the lifter’s highest adjusted Robi score that is not one of those first three.

Robi Score (and Adjusted Robi Score)

IWF Robi Coefficients

Filed under: weightlifting — Tags: , , , , , , , , — Michael @ 16:07

The International Weightlifting Federation updated its Robi Point Calculator, but I could not find the coefficients they used for them. The formula for calculation of Robi Points is as follows:

Robi Points = A x Totalb
Where A = constant of the bodyweight category
and b = constant of the progressivity
Factors defining “progressivity”:
Max. Points for the World Record = 1000
WR = 50%
Points = 10%
(50% of the WR gets 10% of the max 1000 Points)1

By back-calculation, the A and b coefficients for the new (2018) IWF weight classes are as follows:

b = 3.3219281 (This should always be [log(10)/log(2)] using any base of logrithm.)
Class World Record A
45 191

California Propositions — November 2016 — FAQ

For my thoughts on all of the California statewide propositions and Los Angeles County measures being voted on in a couple of weeks, click any proposition below:

Statewide propositions

Prop 51 — $9 Billion General Obligation Bonds for schools and community colleges

No. Funding is awarded on a first-come/first-served basis, so those with the resources to get applications submitted for projects get the bulk of the funds. But the poorest schools, which are most in need of these funds, do not have the resources to get applications approved ahead of wealthy schools. If there were a way to ensure that the schools most in need of the funds would be the first to get funds then this might be a positive measure.

Prop 52 — Extends existing fees on hospitals to fund Medi-Cal


Prop 53 — Mandate voter approval for Revenue Bonds over $2 Billion

No. Revenue bonds get paid for by the projects themselves, not state taxes. The whole state should not have to decide if a project benefiting a local community should get funded.

Prop 54 — Require Internet publication of Legislative proceedings

Yes. The more we know about the Legislature’s business, the better.

Prop 55 — Extends existing tax on income over $250,000 to fund schools

Yes. People who make over $250,000 per year do not need a tax cut right now.

Prop 56 — Raise cigarette tax from $0.87 per pack to $2.87 per pack

Yes. Raise funds to help smokers pay for their own healthcare. Tobacco companies oppose.

Prop 57 — Allow parole for non-violent felons. Also specifies that Juvenile Court judges will decide if juveniles get tried as adults

Yes. We need to incarcerate fewer non-violent offenders. This might help alleviate the racial disparity in state prisons. Also, juvenile court judges should be the best-equipped to decide if a juvenile should be charged as an adult.

Prop 58 — Allow dual-language immersion programs in schools

Unsure. I do not profess any expertise in the teaching of English to English-learners. I wish this were up to experts (and not up to us voters).

Prop 59 — Requests legislature to oppose Citizens United decision

No. This proposal does absolutely nothing real. Regardless of my position on Citizens United, this proposal is a waste of time that does nothing other than to ask the legislature to oppose a US Supreme Court decision; it does not enact any laws at all.

Prop 60 — Require condoms statewide for porn shoots

No. Is this a problem?

Prop 61 — Prohibit State from paying more for drugs than the Veterans Administration pays.

Yes. One step towards decreasing the prices of drugs.

Prop 62 — End death penalty in State. Replace with life-without-parole

Yes. Either you are in favor of the death penalty, or you are opposed. I am opposed. We could argue endlessly about the moral right to end people’s lives, but I am definitely not comfortable with the possibility of putting an innocent person to death.

Prop 63 — Require background checks to purchase ammunition

Unsure. There are a few good things in the proposition.

Prop 64 — Legalize recreational use of marijuana

Yes. Marijuana is nearly legal in California with how easily people get medical-marijuana cards. But, then again, I do not have children, so the scare-ads do not scare me as much as they might others.

Prop 65 — Require all $0.10 grocery bag fees (if any) to go to State

No. Why add another bookkeeping task to what grocers already have to do … just to make the state a measly 10¢?

Prop 66 — Speed up death penalty. Pays for more lawyers to expedite proceedings

No. I oppose the death penalty, so I definitely oppose making it go faster.

Prop 67 — Prohibit single-use plastic grocery bags statewide

Yes. I am happy not to see nearly so many plastic bags floating around on local streets, but I am always surprised that they still show up in other areas. And I do not see many people or businesses losing money locally.

Los Angeles County Measures

Measure A — Increase property tax by 1.5¢ per square foot (for parks, beaches, and rivers)

Yes. Sure. I will pay an extra $15 per year to help maintain the parks that I use.

Measure M — Increase sales tax by ½¢ per dollar (for Metro projects)

Yes. I ride public transport, and I will ride even more if there are trains, subways, and buses running close to the same time as cars (and sometimes faster).

Kennedy’s Undelivered Speech

Filed under: General — Tags: , , , , , , — Michael @ 11:46

On the day John F. Kennedy was killed, November 22, 1963, he was on his way to deliver a speech in Dallas, TX, related to US security matters. Here are a few excerpts:

We cannot expect that everyone, to use the phrase of a decade ago, will “talk sense to the American people.” But we can hope that fewer people will listen to nonsense.

The United States is a peaceful nation. And where our strength and determination are clear, our words need merely to convey conviction, not belligerence. If we are strong, our strength will speak for itself. If we are weak, words will be of no help.

For this Nation’s strength and security are not easily or cheaply obtained, nor are they quickly and simply explained. There are many kinds of strength and no one kind will suffice.

Finally, it should be clear by now that a nation can be no stronger abroad than she is at home. Only an America which practices what it preaches about equal rights and social justice will be respected by those whose choice affects our future. Only an America which has fully educated its citizens is fully capable of tackling the complex problems and perceiving the hidden dangers of the world in which we live. And only an America which is growing and prospering economically can sustain the worldwide defenses of freedom, while demonstrating to all concerned the opportunities of our system and society.

Full text of undelivered speech.

Windows 10 Takes Port 80

Filed under: General — Tags: , , , , , , — Michael @ 13:58

In trying to run a server that listens on port 80 (successfully on Windows XP and Windows 7), I found that the service could not attach to port 80 after I updated to Windows 10. It turns out that, as part of the upgrade, Microsoft has the “World Wide Web Publishing Service (W3SVC)” listen automatically on that port.

The fix: run “services.msc”, stop the World Wide Web Publishing Service (W3SVC), and then change its Startup Type to either “Manual” or “Disabled”.

Thanks go to DeveloperSide.NET for pointing this out!

Lava Falls Rapid — July 2, 2015

Filed under: General — Michael @ 11:19

Eric, Beth, Rex, Amy, Christine, and I paddled together through the Lava Falls Rapids on the Colorado River in Grand Canyon. Our guide, Tom, led us through flawlessly. Many thanks go to Outdoors Unlimited for the spectacular week-long experience! On this day (July 2, 2015) the river was flowing at about 17,000 cfs.

The rapid went smoothly for our boat (the first paddle boat of our group to go through), but after those quick thirty seconds passed, we spent the following two and a half minutes positioning ourselves for swimmers who washed out of their boats behind us.

Everyone from our four paddle rafts and four supply boats eventually made it to Tequila Beach for our overnight camp. Marco arrived nursing a sore knee from an impact in the raft.
