383 cam advice?

Normally, like Richard was saying and eluding to, the tighter 108 would peak higher and earlier. I also was surprised. Also as Richard was saying, there are generalizations due to what is normally seen and exceptions which we have just seen. In this case the top end of the 108. But basically this is what happens.

@273, good video post. I did t know Rich did that test.
