Blodg,
So in your test you did not even the tiller of the bow, and you did not move the nock point so the arrow was 90degrees to the bowstring, you shot whatever arrows you used to shoot regardless of spine and prior rest requirements.

And the whisker biscuit still managed to give you a 3" group at 20yards.

Imagine what the results would have been if you tuned the bow to work with the biscuit instead of against it.

Good luck hunting >>>------------>
