I was playing with the softChrono program a bit and am trying to sort the data.
With the microphone at the breech, Three significant events are recorded.
The first is short and crisp (metalic?) I assume the striker impact on the valve pin and stop block. 0200
The second follows after 100+ ms,The gas release?
Then there is a third event (bounce) after an additional 40 ms.
My limited testing did not confirm the exact reproduction of acoustic events, but indicative.
Question: Does a 100ms "lock time" seem right for a QB with no mods (on CO2 in summer, at low tide....
I will dry fire when the carts expire and record the signature of only the mechanical events, separate from any pneumatics.
That should give an additional look at events.
