IIRC that test MDT did was with a 6.5 Creed. A larger case with more powder/ gas will perform differently with more or less ports, port angle and design all plays into that as well. My favorite brakes right now are from MBM

I have a 5 port Super Baby Beast on a 338 ultra that's 9 pounds all up and watched the steam and lungs come out of my SD buck at the shot from 286y on 14X. He never left my field of view. That is pretty effective mitigation from a very slim brake.
Something has to remain a constant variable. MDT load charge and cartridge were the same. MDT used their line of MBs with different number of ports to find out their point of diminishing return (goal). The 4-port outperformed the 5-port.
Nathan also used the same load charge and cartridge but used his own MBs with varying design and number of ports vs. competitor's MBs to test recoil reduction (goal). They have different goals.
However, in Nathan's test (1st two MBs) the 5-port beast brake outperformed the 4-port beast brake, unlike the MDT"s test result.
I watched several YouTube videos and decided on the APA Gen 3 fat bastard five-port brake for $150.

Great choice! I use these and I feel they work very well.
I deal with this daily.
We make our 1 and 2 port brakes with a different port design. Its extremely effective, but makes the brakes have a longer OAL. Our 3 4 and 5 port brakes have a different port design to keep them at a minimum length and weight but perform extremely well.
The 2 port .990" brake has almost exactly the same performance when tested our 3 port .990" brake. This is because the shape, and surface area of the 2 port designs. The two are almost equal because of this.
People constantly ask "how much recoil will it reduce?" Anyone who tries to give you an exact number doesn't know enough. I can guess, and get close. But its dependent on rifle weight, cartridge, bullet, stock shape, chassis or carbon stock, powder type and charge, and I'm sure I'm missing some.
I could talk about it more in depth but we are moving our entire shop around in order to get a new machine in here!

I have one on one of my 300RUMS and works well.
Terminator T3 and T4 are on the other 2.
Terminator T4 on my 30-378. IMO the
Terminators are the best, but they do direct the blast closer to the shooter.
