ok, when they cut the magnaport slots in a say 26" barrel, the ports take up approx. 2" of barrel, the barrel length stays the same but the gasses exit at 24" so your actualy only shooting 24" barrel velocities. when you put a brake on it you add the brake to the existing barrel length, so you don't lose velocity is this not correct?
I've shot magnaporting, boss, vais, and QD Holland brakes, they're all loud, but the magnaporting hurts my ears worst of all, followed by the boss, the vais and the holland brakes in that order.
I shoot alot of long range targets, and shoot deer at extreme range where seeing the bullet impact through the scope is imperative, I'll take the holland brake every time, more and bigger holes for the gas to escape more of a big boom than the sharp ear piercing crack of the magnaporting and the brakes with various small round holes in them.

The tip of the bullet will be at the end of the barrel by the time the gas is released, you don't lose any barrel length orvelocity.
We checked noise levels with a decible meter, the question came up about noise. fact is they all make the firearm louder. All we had at the time were 3 Winchester model 70's. The first one with no brake...161 DB, the second with mag-na-port...163 DB, the third was a boss 167 DB. We did not have a vais or a QD Holland.
If this were true, you could just magna port the last foot of the barrel and take off even more recoil without giving up velocity. I think you need to rethink the physics of this.
Take a barrel and shoot it over a chrono, then manga port it and shoot it over the chrono again. I'd bet my house on the results.
We did, and your not listing, THE TIP OF THE BULLET IS EXITING THE BARREL WHEN THE GASSES START TO RELEASE
