Default RE: P&Y and 65% let off?

Bogobble, I am not a spokesperson for P/Y, but I do hunt within there perameters and if I have the oppurutunity to bag a trophy I know that I can qualify, but I am sure a person can read into the by-laws and maybe change them in there favor and yes that one in not drawing back at full draw is true, this is how P/Y and defines it , " The maximum let-off on a compound shall be measured at a point in the draw cycle after the peak draw weight has been attained. It shall be measured near the end of the draw cycle where the minimum holding force is reached. This point in the draw cycle of a compound is known as " the bottom of the the valley." Determination of the percent of let-off: The values of the peak draw force and the let-off force shall be used to calculated the percent let-off. The peak force is the maximum force obtained dureing the draw cycle. The let-off force is the lowest force reached following the peak force during a single uninterrupted draw cycle. In all cases, both the highest and lowest force shall be read from a scale during a single and continual pull conditional, without relaxtion. This technique eliminates the introduction of hysteresis, which can distort reading.

Percent of let-off =
100x (Peak Draw Force-Minimum Holding force)
Peak Draw Force

The nominal percent of let-off for hunting bow shall be a maximum of 65%. It is recognized that variations in draw length and/or draw weight can affect the percent of let-off on compound bows. For these reasons minor variations in let-off are acceptable.

If you are within a 5% tolerance, I think you can qualify. If you could care less about a P/Y then don' t bother applying. For the trophy hunters on this board , these are the standards that we are govererned by and if a person can' t meet this criteria, then don' t play.
