Occasional right misses are often caused by plucks.
Consistent right misses for a r/h shooter due to form errors aren't as common as left misses. There must be 40 ways to miss left!
I would first look at arrow spine, and next look at centershot. If a bow is cut 3/16 past center, and you are using really skinny arrows, you may need to build out the strike plate so the arrow tip is slightly outside the center line of the bow to get good arrow flight. If arrow spine and centershot are okay, you can move the POI a few inches to the left by using a stiffer strike plate material. In other words, use a plain leather strike plate instead of Velcro or rug.
