I think somewhere someone did some tests with a mic near the valve measuring spring bounce on the nock open valve, so perhaps the opening times are out there. We know the lock time, so perhaps they can be compared.

But I think we're going off the track a little here. If the idea that a downrange chrono can pull out a bad pellet as a reason for a bad group then we need more data.
