Testing Parameters:

A force-draw curve was obtained from the reviewed bow, using a digital force gauge with a resolution of 0.1 lbs. Measured draw weight @ 28 inches was rounded to the next half pound.
The different arrow speeds were achieved with the bow shot from a shooting machine with a mechanical release and also hand held with finger release, using a "Crick-It" clicker and a deerskin glove.
The string was pulled to 28" A.M.O. which is 26 1/4 " from the string to the deepest point of the grip. The (3) arrows for the speed testing had a weight of 9 grains per pound of measured (not stated) draw weight. A 16 strand flemish twist Fast-Flight string without any attachments (silencers, etc.) was used.
Speed measurements were taken three feet in front of the back of the bow with two chronographs set up in a tandem configuration. Each arrow was shot a minimum of six times and the average speed was rounded to the next whole digit.
