Counterexample?

In Response To: Counterexample? (eXtreme Gammon)

"VR := 1 / (1 + exp((0.5 - VR) * 4)); This insure that a player cannot be more than 100% (or less than 0%) favorite. The slope is 1 around 0.5 so for most practical uses the value reported is very close to the difference of luck MWC."

Suppose I am doing a play from here position but want an overall equity as if it were a rollout. Is there a nice way to keep stats for that? I just looked at the VRR result for each game and did my own stats. If I am doing that I really want the real VRR instead of the adjusted one.

Another place that the real VRR would be needed is suppse players A and B play a poistion and bet on the win chance of A and use the VRR result. For example A says he can win it more than 5% and B says no so they play it out and payoff is according to VRR result - 5% times a stake.

It is possible to undo the adjustment of course but could there be an option to get the real VRR instead of the adjusted?
