What is the relationship between arrow speed and draw weight?. Obviously arrow speed will increase as draw weight increases, but at what rate. How many FPM do you gain with a lb of draw. Would this be a dynamic number, i.e a % of increase?

Sorry for all the questions, I was just wondering what effect increasing my draw weight form 68 to 70 lbs.

Depending on the bow you get between 1.75-2.25 FPS for every pound of adjustment.

So say 2fps on average per pound of draw weight.
