and do you thing to make this calculator for windows or windows mobile? Dick Baugh 08/06/08 : I use Accurate Sights software from someone in Australia.It also includes compensation for aerodynamic drag. Dick Baugh 10/06/08 : Comparison with Accurate Sights software: Matched at 20 and 70 yards.
SURFELITE 10/02/10 : i am also doing a science fare project for my freshman class. can someone post something/someway to help me fine a way to figure out the acceleration,velocity, and speed of a normal pull back tension of the bow a 45lbs.
plz some one help me out this project is due next tuesday and i have nothing.
Yours is 4.2 inches low at 10 yards, 8.3 inches high at 50 yards and 44.7 inches low at 80 yards relative to Accurate Sights which includes air drag and distance from eye to arrow. The aerodynamic drag is not taken into account as it impossible to do with only 4 inputs.
This program was meant mostly as an easy way to estimate your arrow speed.
Perriswood Dick 30/03/07 : I can see how the algorithm accounts for different arrow size/weight but where is limb/r1ser length and draw weight taken into account RLH Apostolos 01/04/07 : In fact, we don't care about the draw weight but only for the angle difference between the two distances. I was also thinking of doing another version that could calculate your arrow speed loss per meter given all of your sightmarks. Could you please help me figure out how to measure speed of an arrow (point blank) just with draw weight (45 lbs) and arrow weight (385 gr)?
