I have a Holton cornet from 1911 and it has essentially no compression any more. My grandfather used to oil it with spit. It is a great player though, in tune, secure feeling. The same more or less applies to my 1938 Heckel rotary Bb. Incredible player. That would imply a great overrating of compression when applied to the valves of trumpets.
Current building practice for rotary valve even has a hole drilled in the part of the valve casing not used for rerouting the standing wave. The valve no longer pop at all. Only the standing wave routes are really tightly sealed.
I am not sure that every trumpet needs snap, crackle, pop.
Whenever I feel blue, I start breathing again.
I wonder if players who can produce a tone more efficiently use less air which lessens the need for perfect compression.

Don't be afraid to try something different. The Ark was built by an amateur and the Titanic was built by a group of experienced engineers.
By the inch it's a cinch, by the yard, it's hard!
Guys, all of you have completely ignored that the third valve slide is a longer than the first slide, therefore has a greater volume of air in it. You pull it out about the same amount and the vacuum in the first slide will be a lot higher.
