His error is still 0.56. There is more of a case for adjusting your
error by:
-0.078 - -0.56 = +0.482 i.e. a positive blunder in your favour.
Do you go back to Move 1 and also adjust the -0/048 error? If Move 2's
correct action was ND/T, would move 1 still be re-evaluated? This is
what I was referring to when I talked about taking future moves into
account - future from the current move's POV.
I can understand the desire to reward error-inducing plays, but I think
that it is impossible to come up with a logical and consistent
framework. You are trying to analyse the meta-game, not the game itself.
