So, I had my 101st Airborne in the vise today, and decided to take a few measurements to see where I'm at now after shooting heavily for the past 6 months. I found my brace is still dead on, my cams are synched (finally got my modular stops hitting the cables at the same time after a lot of tweaking), but I'm at 36 5/8" ATA. How much can this difference (from 36 1/4") effect my my poundage? I don't have a scale, but I'm shooting 60lb limbs backed out to ~58lbs from what I can guess. This "guess" is probably off even more due to my longer than factory ATA. I've heard there are tolerances built in by the manufacturers for deviation above and/or below factory specs, but how much? Could this effect tuning at all? The reason I asked is when I broadhead tuned this summer, I had to back my poundage off a bit to bring my broadheads in to my field points. I would never had guessed ACC 3-49s, at 28", and 60# would be too weak of spine, but that's what my BH tuning showed (although I was able to get them pretty close by dropping a few pounds. So...thoughts?
