    Another Math Question

    I just had my bowstrings replaced and clearly gained some velocity. My old strings were sighted in. New strings shot 8 inches high. How many FPS did I gain with the new strings?

    I did not chronograph either string.

    Knock moved, peep moved, or both. Unless you had a lady estimate the 8" based on what they have been told. No way new strings gain that much speed.

      You can't correlate point of impact to velocity alone.

        Odds are your peep is higher

          I think yall are right, but I was having fun with the math trying to figure it out (as if velocity change was the only variable that changed) and got stuck

                  If new string are shorter than the old stretched out strings that would increase the brace height and shorten the power stroke and reduce velocity??????

                    Is this based on acceleration by gravity to drop the arrow 8 inches to a target 20 yards away.

                    I can figure time to drop 8 inches but get stuck after that. Its been a long time since college physics class!

                      No sir. I picked a 3 and then I picked a 6. They were right there on the keyboard.

                        Nocking point on new string is lower than old string or your peep sight is higher. Enough said, anymore thought is a waste of time.

                          Curt is wrong!! It's 32

                          (For the same reason)

                            Fair enough. Guess I'm the only one who likes thought experiments

                              But with longer string the draw weight would be less since limbs would be more relaxed for lack of a better term thus making it slower
