Arthur, just another thought as long as this subject is fairly recent.

You mentioned hysteresis in some of your posts. Hysteresis is a static measurement. I checked with some info I had saved from Norb (like I posted about VM) on hysteresis.

As I mentioned, the hysteresis is measured as the difference between the draw curve and letdown curve. It is the STATIC friction of the bow- and it has nothing to do with an arrow of any kind.

Norb mentions that static hysteresis has no direct significance as related to the DYNAMIC performance of a bow since it is measured under static conditions. But generally, bow with high static hysteresis show lower levels of dynamic efficiency (higher VM).

Norb likes to keep the static measurements totally seperate from the dynamic end of things. I see why as you don't want to be mixing apples and oranges. Well, I don't know if I would go so far as to say that hysteresis has NO DIRECT SIGNIFICANCE related to the dynamic shot (which is what Norb said)- there's gotta be some sort of link to high friction in a static condition to poor dynamic performance.

Like we talked about, the VM accounts for ALL losses in the dynamic shot, so I would venture to say that the hysteresis has to factor into that somehow. I can't ever imagine how you could have poor static friction, yet have good dynamic efficiency.

just some more food for thought.....
