MeanV, clean up your PM box !!!

I outshot a fellow bowtech shooter at the range tonight, Vegas rounds at 18 yards.
I shot a 271 ( 9's all the way, five x's and four 8's )
The guy with the General blamed his misses on the sts rubber V shape, he said sometimes the string hits the flat outside of the V shape and his arrows get twanged left or right. Is he right about that ? I checked out his shooting and he has good form and follow through, his rest is in the right position and he shoots good arrows.
The string is right in the middle of the V shape when let down.

Any advice, Cuz I want to beat him again after he fixed his problem !!!
