I wonder how many P coins are actually D or S, but too weak to show.
Probably not so much that - the weakness in
Peace dollar strikes is at the periphery. Look at a few of them. You'll see flattening of LIBERTY towards the rim, and on the reverse PEACE will be weak.
A full set of
Peace dollars in MS63 or better, with what can be considered a "full strike," is a difficult accomplishment indeed.
