Dan, No. You've got it. Nearly 100% of our P22s go through this. Unfortunately the newer ones need such regulation the 1st year! Bobbling hammers caused by shrinking key travel... Pianists will tolerate a wider range in blow on uprights. A difference of 44-46mm blow doesn't seem to matter on a P22. (Maybe because it's a P22?) I tend to vary blow and keep dip at 10mm on uprights. And as I said, I rarely sacrifice letoff like I've seen some do.
