With the F#2 module on it, the post should be set at approx. the 6.7 mark for 80% let off.
To make it 29" draw at 65% let off, you'll need to use an F#1.5 and set the draw stop at approx. the 7.0 mark.
This is counting from the bottom (L) end of the cam to the middle of the draw stop screw head.
The longer lines are the whole numbers and the shorter lines are the 1/2 numbers.
