The 20 degrees up and 10 degrees down is the differential action that helps the KR to make turns with no rudder input. I guess if it dives you have to correct, but you've already got your hand on the stick. Mine dives a little in left turns, climbs in right turns (or I may have that backwards), for whatever that's worth. I did some of the differential thing with the bellcrank, and some of it with Frise ailerons, and it seems to have turned out pretty well.
