If one of the main reasons that a shorter brace height is harder to shoot accurately/consistently is the fact that the arrow stays on the string longer, then.... wouldn't shooting a heavy (slower) arrow have almost the same effect??

You are making my head hurt...<img src=icon_smile_tongue.gif border=0 align=middle>
If you could hold all other variables constant, then I would guess that you are right. The 'lock time' from release to arrow launch might be the same between a low brace height bow with an 'average' weight arrow and a high brace height bow with a heavy arrow. But there are so very many other variables that come into the equation that you may never be able to isolate the accuracy variance.
The most important part of the archery equation is shooting form. If we could develop perfect form, the brace height issue becomes moot.

It's not the amount of time...when people say it stays on the string longer, they are referring to distance travelled...the arrow stays on the string longer because it's travelling a further distance. The heavy arrow and light arrow have to travel the same distance...time-wise there might be a minute difference because of arrow weight, however it would be insignificant compared to the distance.

Well..... there's two way of looking at the long vs. short draw length. If you have a 25" draw archer who is torquing the riser 2 degrees, and then a 32" draw archery who is torquing the riser the same 2 degrees- it's a wash, even though the 32" archer may be torquing a greater amount (distance wise), because of the longer draw it is still the same angle of torque. Now on the other hand, if you have both the long and short draw archers moving their strings at full draw 1/2" to the side, the short draw archer will have more of an angle due to the short draw. Make sense?
But as far as brace height, the closer the arrow on the string gets to the pivot point of the bow (your hand mating with the throat of the grip), the more magnified any small torque errors become.
You can do an example of this right at your desk. If you grab a pencil 1" from the eraser end between you thumb and index finger and with your other hand grab the eraser end. Move the pencil shaft back and forth 1/4" while keeping the eraser end still. Note how much the point end is moving around. Now do the same thing but this time grab the pencil 4" from the eraser end. Do the same movement of 1/4" back and forth while keeping the eraser end still. Note how much less the point end swings as compared to the first scenario.
You can see how that as arrow on the string approaches the pivot point, any side to side toque error is magnified the closer the string gets to the pivot point.

Jeff,
So then is a 30" draw shooter severely handicapped compared to a 26" draw shooter???

I just read somewhere that all the top winning target shooters right now have shorter than average draw lengths. So maybe us little guys do have an advantage after all. I don't know where I read it or how much truth there is to it, most likely on a forum like this one. Maybe that's why women can out shoot men, they shoot a more forgiving set right off the bat( short draw length lower poundages).

Blackfrog,
I was always under the impression that the closer you are to pivot point the LESS movement there is. That is why an overdraw - moves the rest AWAY from the pivot point, and reflex designs - move limb pockets AWAY from pivot point both hurt accuracy. I cannot see how having the arrow release closer to the pivot point hurts accuracy.
I am not trying to bang heads with anyone, I am just confused<img src=icon_smile_blush.gif border=0 align=middle><img src=icon_smile_tongue.gif border=0 align=middle>

RA-
I should've clarified my statement a bit more. By pivot point I meant the cradle point where the prongs hold the arrow- which ideally for the most forgiveness would be directly above where your hand rests in the throat of the grip. The farther back the overdraw, the more magnified and riser torque will be. And also the lower the brace height the more magnified the errors will be.
If the prongs cradle the arrow directly over where your hand meets the throat of the grip, that is the position that has little or no movement if you torque the riser.
If the arrow is on the string closer to the pivot point, the more touchy things become as well, like I mentioned in the previous post. Imagine the first Indians making their first experimental bows- I'm sure they learned real quick that a bow with only a 0-1" brace height was REAL tough to shoot. The arrow would still be on the string almost right up to the riser, errr- I mean wood stick. If the approaching string (with the arrow on it) is ANYTHING but perfectly straight, the errors become worse the closer it gets.
Imagine the incoming string was not perfectly straight towards the riser, but with the limbs at full draw the riser is torqued. Even though the contact point of the arrow is directly over your hand, the string will be not be coming directly to that point because of where the limb tips are (at full draw) and the torque applied.
