As Bob stated, this is going to become a bad assumption when you improve your
positional knowledge.  Especially in endgames where passed pawns often score
several times their usual value purely because of their position.  Obviously a
pawn about to promote is worth almost the same as a queen.  Things like passed
pawns should be included in your rough positional estimate.  What I do is make a
rough guess (lazy eval) to the position including everything that should make
the score vary by a lot.  Then if this falls within a certain window I calculate
a more accurate 'proper' eval.

Cheers,
