For every Manufacurer Spec change you make you are changing another...even if you have ATA, BH, cam timing, Idler lean,center shot etc...you can still be off on draw weight or draw length
Twisting the cable affects the draw weight very fast..but at same time increases draw length...so one has to watch all the specs as a bow is spec tuned...sounds difficult but one can get all spec 100%
Below is my chart that shows what twisting what does..
