In Response To: Cube error rates (Joe Russell)

The score (after 0 games) is: White 0, Blue 0

Move number 10: Blue on roll, cube decision?

White	114
Blue	114
Position ID: 2xbUgEDbFtSAQA Match ID: UQkAAAAAAAAA

Cube decision
2-ply cubeless equity		+0.3967
	0.5869 0.4396 0.0730 - 0.4131 0.2606 0.0291
Cubeful equities:
1.	Double, take	+0.5768
2.	Double, pass	+1.0000	+0.4232
3.	No double	+0.5225	-0.0544
Proper cube action:		Redouble, take

Let's say your error here in not doubling is .05. This assumes that after fan/fan you will cube. But after fan/fan you won't cube...so your error is compounded more than .05 would indicate. So regarding the error as just .05 isn't sufficient.

If, on the other hand, you doubled a position where the ND error was .05, you would deprive yourself of a chance to make future mistakes.

The score (after 0 games) is: White 0, Blue 0

Move number 11: Blue on roll, cube decision?

White	107
Blue	107
Position ID: 2zaogEDbNqiAQA Match ID: UQkAAAAAAAAA

Cube decision
2-ply cubeless equity		+0.2594
	0.5519 0.4196 0.0794 - 0.4481 0.3042 0.0393
Cubeful equities:
1.	No double	+0.3830
2.	Double, pass	+1.0000	+0.6170
3.	Double, take	+0.3062	-0.0768
Proper cube action:		No redouble, take (11.1%)

So here the error really is .07, right?
