A bow which has a 6" brace height and is set for long 30" draw length will have roughly a 24" powerstroke.
This assumes draw length minus brace height = power stroke which is not correct. Brace height is the distance from the string to the deepest part of the handle. Draw length, that is traditional draw length, is the distance from the string at full draw to the front of the riser which is accepted to be a point 1 3/4" from the deepest part of the handle. Therefore the power stroke for the example used is 30-1.75-6=22.25 not 24.
You are right Sylvan. I contacted the web site mentioned and they were very quick to reply. This is what they said as I was kind of thinking was the case.
>>Officially, you are right. I think the concept was simplified for the
purposes of illustration........that's why the "roughly" term was inserted.
However, the official AMO draw length would be measured to a point 1.75"
beyond the pivot point of the grip (with the bow at full draw). This
happens to be the same position from which brace height is measured (when
the bow is at rest).
So technically, a bow's powerstroke length would be draw length minus the
brace height AND minus the 1.75"...

Nice people there. The site did state that not all bows are the same and the differences would be roughly the same. Mine is only a 1" difference. Thanks for pointing that out.
