No, you misunderstood.  Add 2 inches to the front of the ski at whatever a common degree of early rise would be.  So the ski goes from a 178 to 183.

So I did the math wrong, add 4 inches and make a 188 powder ski while retaining the skiing characteristics of a 178 groomed snow ski.  After all, isn't that sort of where rocker has come.  Initially it was reverse sidecut, really wide underfoot, and lots of rocker; then less rocker and more normal sidecut, and it's continued to morph into blends that provide some (to lots of) edge on groomed while still having the advantages of rocker off-piste (minus the reverse sidecut of the Spatula like skis).
Ski lengths are cm, not mm so 51 mm is only 5cm.
