especially the piece-square tables aren't so much about putting an accurate value on a position as they are about making sure that the chess engine follows certain heuristics about how to develop your pieces. For instance the pawn-square table will make a chess engine play a conventional opening and then try to advance its pawns, the queen-square table will tend to move the queen towards the center of the board but not very strongly so it will develop other pieces first, etc.
