I did some checking on my Allegiance today concerning twisting the string to change draw length. I took out 6 twists and checked the ATA, brace height and draw length. As close as I could measure, the ATA increased 1/16" and the brace height increased 1/16" also. Draw length was also increased by 1/8" and the let off seemed unaffected from the factory setting at 80% let off. I would expect that by putting 6 twists IN the string that draw length, ATA and brace height would be decreased the same amount also.
Looks like the Equalizer cam system can be easily fine tuned for draw length. I didn't weigh the bow, before and after changes were made but it seemed to have no affect on draw weight.
Because the actual AMO draw length was a bit on the short side of a 29 inch draw length, I ended up leaving 4 turns out of the string from the factory setting.
The birth certificate said that this bow shot 317 fps through the factory chrono and I got the same speed with my chrono also with a 301.4 grain arrow.
I'm wondering now,, with 4 turns out from factory,, am I now shooting 320 fps
