Rangeball.. I agree with you on that. Take the Bowtech Infinity cam for instance. You adjust the letoff by adjusting the draw stop.. If you set it for 80% letoff.. the drawlength is a bit longer than the 65% setting.. and when the string is released.. the cam must spin past the 65% setting. I never tested to see if the 80% setting was actually faster or the same as the 65% setting.
