I'm shooting a patriot single cam vft. my module is a #4 post setted at 5.5(5.5 from the L on the cam). I originally wanted a 27 inch draw at 80% let-off , but after seeing the chart I think my draw length is 27.5 , and 28 with my loop , because on the chart for a 27 inch draw and 80% let-off its a #4 module post setted at 8.5 , so since i'm at 5.5 it must be about 27.5. Am I right??

well after shooting it alot I find I can't keep my form very steady and I want to change it to a 65% let-off. I know I can change it to a #3 module and post set it at 8.5 for a 27 inch 65% let-off bow, but I think It might be a little short?? And if I move the draw stop towards the L (long) side then My let-off will start to increase , probably bringing up to 70% let-off or so??

So My question is , what do I do to set my bow to 27.5 draw length 65% let-off.??

thanks alot
