Can you say definitively it's not physically possible? Fluids are weird and sometimes exhibit unintuitive behaviors (at least in my experience). Also how do you quantify blast? Aero/fluids engineering is not my field of study or expertise so genuinely asking.
All good, ask away anytime.
The more gas you redirect, the higher the intensity of the blast (because the pressure will be higher), and because the volume of gas that’s being redirected is larger, the longer you’ll feel it for. The higher the efficiency of the brake and the faster the exhausting gasses, again the more you’ll feel the gas as they will carry that intensity further.
All gas you redirect is felt by the shooter and the more aggressively you direct it rearward, which increases performance the greater the angle, the higher the affect of the blast because it’s directed closer to the shooter.
So no matter which way you look at it, more performance equals more blast coming out of the brake.
Now the only way to reduce how much of that blast the shooter feels with a high performing brake is to use angles to direct the blast in a direction, that compromises and hurts performance the least amount, while creating as much distance between the blast and the shooter as possible.
The chad directs the entire blast upwards at an angle of 15 degrees (our patent pending redirected blast tech) and rearward at an angle of 47.5 degrees. It’s a compromise that doesn’t hurt performance much while creating a lot of distance between the blast and the shooter vs the original tmb. If I tried to add more performance to the chad tomorrow, every percent of performance I added to it, would increase blast to the shooter. There’s simply no way around it.
So it’s not really possible to make a brake that noticeably out performs the chad in recoil and blast at the same time while being of a reasonable size. You might find a blend of angles that combined with really high efficiency internal geometry, technically has a few percent better performance with only one extra percent in blast but it’s not going to be a game changing difference.
The more important factor to focus on differentiate the two would be the personality of the brakes. They do similar things but are very different in design and thus have very different recoil impulses.
