It does not equal to playing strength but certainly add to playing strength
Rybka with endgame knowledge could win the following game
It had an advantage of a bishop but could not translate it to win.
Note that both sides did not use tablebases(maybe movei used only part of them
and I do not know).
Movei with KBP vs KP tablebases has no problem to avoid 102.Rf2 but rybka could
not find
