Cubing against ace pt game

Deciding how much the recube power influences the initial cube is difficult. So I just looked at a couple positions at both money and at various scores and use them to get an idea of how much to adjust from money play knowledge. I looked mainly at the positions 54S 33A F cube and race with leader at 80 pips cube.

For the blitz position it is a .84 take for money but a .87 take for 7a getting cubed by 6a.

For the race a a 78.5% position is the borderline pass/take but at 6a 7a it is a solid pass at 1.085

That is where I got my statements from. I didn't use a math model of cube power. Now for the actual position I may be wrong and the score actually does argue against the score. From the RO the cube is a .057 error for money and a.073 error at the score. So it may be that initial cubes come just slightly later but the cashes come sooner (and I would say it more than just slightly). I am rerolling those positions out with more trials and also do the money rollout without Jacoby which I think is a better comparison.
