bonecollector: Keep in mind that "computer graph plotting" can be misleading. We had one manufacturer swear to us that his product had "perfect" nock travel. We asked him how he plotted the results and then duplicated his procedure when we got back to the shop. After we finitely measured and plotted the results, his test methods agreed totally with our equipment; which was far from "perfect". In fact, it was pretty bad.

I'm not saying anyone's information is wrong. What I'm saying is consider the source.
