Mordecaia,
You' re trying to do too much and " overwhelming" yourself.
I have never bared shaft tuned and I no longer try paper tuning either.
Once I adjust my arrow rest, string loop, and peep, I shoot a few shots to adjust lefts and rights then elevation. Then I shoot a few groups at different yardages.
If my arrows fly straight and my groups look good. That' s it!
I set up my Bowman over two years ago and haven' t touched the settings since.
Same with my Super Nova I set up last August.
I tend to shoot the most " Murphy Proof" accessories on the market.
At least, imo, they are the most reliable going.
To me, this helps quite a bit with keeping your bow consistantly tuned and trouble free.
Like Arthur, I don' t go for any of the drop-away rests and other gadgets.
They' re trouble waiting to happen, jmo.
Actually Ol' Arthur is pretty sharp when it ccomes to explaining things and making them seem simple.
That is why I, also, enjoy shooting my recurves.
Sag.
