I never found any effect of the time control on the scores I measure for
some material imbalance. Within statistical error, the combinations I
tries produced the same score at 40/15', 40/20', 40/30', 40/40',
40/1', 40/2', 40/5'. Going to even longer TC is very expensive, and I
did not consider it worth doing just to prve that it was a waste of
time...

The way I see it, piece-values are a quantitative measure for the amount
of control that a piece contributes to steering the game tree in the
direction of the desired evaluation. He who has more control, can
systematically force the PV in the direction of better and better
evaluation (for him). This is a strictly local property of the tree. The
only advantage of deeper searches is that you average out this control
(which highly fluctuates on a ply-by play basis) over more ply. But in
playing the game, you average over all plies anyway.
