IWF Robi Coefficients

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.)
