Welcome Jim. Looking forward to more of your input.
I usually don't pull my bows as much as you do after each wood removal but I do pull 20 to 30 times...and never over ultimate draw weight or length. What I do is after low brace height has been achieved I will let the bow rest at low brace for at least an hour at first and gradually longer and higher as tillering progresses until I hit the ultimate brace height(for me 5 1/2" to 6"; my fistmele). I believe we are achieving the same goal but with different routes. That's what I find so interesting about wood bow building. There is more than one way to skin a cat (as we used to say as kids).
String follow is only bad if you are trying to get every bit of energy from a bow. If your goal is an effective, smooth shooting bow, string follow(within limits) doesn't matter. If you are trying to achieve zero string follow, wood bows are not for you. Wood is organic and as wood is stressed the cells on the belly side compress and on the back side stretch. You can not prevent this with wood bows but you can limit it. It is the nature of the wood. You can minimize string follow with proper tillering practices and patience. Even if you add 2" of backset and you end up with either a flat profile or slight reflex, you still have string follow, the cells have been compressed or stretched, it just isn't as apparent in the unbraced profile.
