     You are right that "it depends" (on those factors and a couple  
others), but it is true that as of a few years back Steinway went to  
one dip block for all, with "S-D" on the back. Maybe it was just a  
cost cutting move <g>.
     For my part, I like to adapt to circumstance. I often find 1  
3/4" blow just fine, and dip is adjusted to letoff and aftertouch  
based on that blow. Dip as a measurement is low on my priority list,  
though it does need to stay within bounds. .420 sounds like a good  
maximum. .400 is usually plenty. I start at .400, and see how large a  
blow I can get away with (I'd rather not be fussing continually with  
dip if I can avoid it, though it's no big deal to add or subtract one  
or two .010 punchings to or from every key - assuming you planned  
ahead and made sure every key had a couple .010's to begin with).
