In Response To: Which PR average is most correct? (Tenland)
The overall Level used a weighted average of the each sessions based on the number of decision.
The last session has a weight of 1 A game played 10000 decisions ago is weighted at 0.5 A game played 20000 decisions ago is weighted at 0.25 the formula is exp( D / 10000 * ln(0.5))  where D is the number of decision since that game. The system allow to show a more accurate PR as of now, in particular for players who improve.
The PR displayed in the results tab is the raw average (not weighted).
For a PR bet, I would use the one from the results tab.
