My main point about stick grip rotation was less about an absolute number and more about avoiding blindly installing a grip (especially an Infinity Grip) straight forward. 10 degrees, 40 degrees whatever you want just don't near permanently affix your grip without some forethought. I say especially an Infinity Grip because they seem to be more "molded" than say the Tosten grips.
As for the desk test mentioned below maybe pushing away gives an ideal rotation of 5-10 but I doubt pulling gives you the same result. I hope to never have to exert that much pressure on an RV stick. I take that back when doing Power On Stalls in the -10 either solo or with my light weight instructor and half tanks the -10 feels like you have to stand it on its tail to cause it to stall. In that instance I find you might want even more rotation as it feels more like a curling a heavy weight. Man that -10 is hard to stall with power on. I remember being totally drenched after 3 Power On Stalls, followed by the most gentle and predictable break. I love my RV's!

I don't recall doing a power on stall yet in a -10. However, since the
point of the exercise is in a max gross wt and high density altitude
scenario, I would think that one would want to limit power to around
60-70% for such a maneuver if you aren't in fact at full gross.
You want what it feels to take off at gross from Big Bear, Flagstaff,
Leadville, Aspen, etc on a summer day so as to not inadvertently stall
in that situation.
Having all the excess power of a -10 at 30% useful load is not going to
give you any idea of what a typical departure stall feels like.

I tried Power On Stalls in several configurations including right near Max Gross Weight. The Lightly loaded one was particularly memorable that is why I mentioned it. It is the time I recall having to pull most on an RV stick.

Good point. I have flown with a stick that had a bicycle grip with the

'knuckles' straight forward. Really uncomfortable. You can get a good
idea fo the angle if you place your hand in a 'loose grip' and see where
the thumb intersection is in relation to the 2nd or 3rd finger joints.
Just hold the stick grip where it's comfortable. I always thought a
Tosten grip would work really well in an airplane with a center stick.
