I just glanced at the chart and saw the +2.8 at 10 yards for me and really don't find that to be correct for me,after that,I really didn't study it.
Peep site height has alot to do with point of impact at that distance.
My point about 1 pin users is to learn actuall trajectory and worry less about the total drop to best setup a hunting bow with 1 pin.
I personally would never use less than 2 pins.I would set them up to be at the top of the kill and bottom of the kill out to 32-33 yards and never worry about speed or distance.Basically,have a 23 yard pin and a 33 yard pin.Place both on the vitals andjust shoot.
Use a rangefinder for longer shots and hold a little high with both,this would be an extremely effective hunting setup but I use 4 pins and shoot accordingly.
