Rudder throws for good KE?

I am kinda getting max throw of 60mm on one side and 53mm on the other side,
unless i open up the hole further on the other side due to linkage geometry, the servo arm along with clevis is slightly going inside the opening at max throw.

What max throws are recommended for Rudder to hold a good KE? I know it depends on lot of things like speed, cg etc.
