Let me understand. Suppose White has 40 pseudo legal moves when black has 30 pseudo legal moves. Do you give white bonus of 1 pawns? I think that in this case the bonus is too high. I suggest that you try smaller values. I read in the past a claim that a bonus of 0.03 pawns for square may be the best. I think that as a rule it is better to start with evaluation that is too low and not with evaluation that it too high so I suggest that you start with 0.02 pawns for square. Uri
