Also the number of holes comes into play as well right? If the hole count is the same then what your saying is an easy thing to work out. But if there are say 10 holes at 1.1 size or 5 holes at 1.3 the 5 hole piston would have less total hole area and more pack? (11 vs 6.5)
The 5 while would have more resistance at higher shock speeds than the 10 hole?
