<img src="http://img155.imageshack.us/img155/3908/accel.jpg" border="0" alt=""><br>I have analyzed the first high speed recordings.<br><br>Two bands with identical length, identical pouches and identical draw weights. Double TB Gold,<br> full butterfly, one cut 2,8cm x 1,8cm, and the other one 2,3cm straight.<br><br>As you can see, the tapered band was immediately faster than the untapered one, and it also accelerated longer. The straight band reached the peak speed of 69m/s at frame number 26, at 101,6cm. The tapered band set reached the peak speed of 79m/s at frame 24, at 116 cm.<br><br>The rest of the flight added no more acceleration, even though the ball stayed in the pouch in both cases. Quite interesting!
