I’m a little late to the party but might as well throw in my 2 cents. My current rack has a slightly curved rest for the bow to sit on and I usually pull from wherever the balance point is. My previous rack had a strap rest similar to Mocoon’s. The nice thing with that is that you get instant feedback on which limb is stronger.
However, I’m a big believer in finishing tillering (the last couple inches) by drawing in hand and photographing it. There are aspects that you can’t see necessarily but you can feel and I find that helpful.
