Anchor- thumb nuckle at jaw bone. Nose touching fletching/string. Peep sight about 4.75" above nock. I haven' t measured the last one, but on my other two bows with the same 36" ata the peep is 4 3/8" above the nock. This didn' t seem to work very well with the shorter 31.5" ata and I had to move the peep up the string if I wanted a natural anchor/ peep sight relationship. (when I draw with my eye' s closed and then open my shooting eye, I want to be looking straight through the peep. no head bobbing).

Straight fletched- last year I achieved sub 3" at 30 yard groups with muzzy 4 blade 100 grain b/h and straight fletched arrows. I switched to mechanicals mid season and dropped the number to- 2" .
For some reason of the three mechanicals I practiced with(shockwaves,sidewinders and snypers), the sidewinders flew the best & most consistant.

If I have flight issues with straight fletch I will simply fletch up some helical arrows for hunting and use them for just that. Last year I shot both and the point of impact was only slightly different. Still within a resectible group.
