A new sinclair coefficient.

You might notice that the sinclair coefficient has not been updated for this quad.
Apparently the fellow (Canadian, PhD Statistics) who took over doing it, is not interested in continuing.
Its probably not a big deal but I thought it was worth mentioning.

Was there a reason given?

The 2nd hand information communicated to me was that he took a job in a US University and was not interested in continuing in updating the coefficient.

I have heard this as well.
The Sinclair coefficient had its faults but it was still a nice stat to use, as long as it wasn't treated religiously (which it usually is).
Weightlifting has quite a few mathematicians in its community, hopefully someone wants to step up to it but it's a lot of work.

So, in the last few days IWF actually distributed a new Sinclair formula!
Apparently has been sent out to member nations, so expect some sort of public statement soon and recalibration of the tool on the iwf page.

FYI Marc Poretti updated the new Sinclair coefficents (SC) for the 2021-2024 Olympic cycle (prior to this thread...) and it was recently distributed to national federations.
Updated values
Men's
A: 0.722762521
b: 193.609kg
Women's
A: 0.787004341
b: 153.757 kg
SC where athlete BW is less than b, is given by 10
AX2 where X=log
10(athlete bodyweight/b)
SC where athlete BW exceeds value b is 1.

I'm told (can't be confirmed) that the reason for his reluctance was due to the IWF implementing the Robi points as a seeming replacement. However after the farce that was Tokyo qualification, he realised they were fucked.
