Bob, no, I really don't. From 9- 10: O'clock is pretty standard, different positions for different body structures.....however, if you get abovee 10:00 O'clock, you can run into some negative issues.
Here's my elbow on a level shot...probably around the 9:15 position....
Please be aware...The elbow doesn't just 'come back farther'...it comes around in a 'J' shape. Do not be afraid to 'cozy up' to your anchor.
BODY POSITION :
Not this.....
But this...
Not this(red line)...this causes a 'fly away' release and bow torque.
