ATA is defined as the initial velocity of a 350-grain (23-gram) arrow when shot from a bow with a peak draw weight of 70 ± 0.2 lbf (311.38 ± 0.89 N) and draw length of 30 ± 0.25 in (76.20 ± 0.64 cm). IBO speed is defined as the initial velocity of an arrow with a weight of 5 grains (0.32 g) per pound of draw weight.

When the archer commences the draw, mechanical advantage is at its greatest and the bow limbs are only pre-stressed to the strung position; therefore drawing weight is at a minimum. However, the drawing weight rapidly increases because mechanical advantage reduces (consider the string is pulling more and more directly on the limbs) and stresses ...

Paterson, Chairman of the Society of Archer-Antiquaries, believed the weapon had a supreme draw weight of only 80–90 lb f ...
