However, I can't feel the difference between the 4PLS w/R304 at 5.5 and my 4PX w/R304 at ? In Hand feel,i liked the 4pls a little better than the 4px but that's probably because I used the 4pls for so long I am used to it. So I really wonder, once we get down to sub 5ms how effective is the cost per benefit at this point? All my servos are in the .07 to .12 range so they are likely the bottleneck at this point. I'm running Futaba s-bus Gen servos but they're not the latest and newest so I'm not sure I'd benefit from the 7px. Not yet anyway.
I think the reason you weren't able to perceive a difference between 4pls and 4px running on R304 is because they probably have almost same latency. You can kind of imply by using the same receiver you will have the same frame rates of transmitting and receiving. The only thing that will make a difference is the TX signal processor basically. But it's all speculation at this point until someone conduct the test.
My personal take on it is you can probably feel the difference in speed between a 4px and m12s but it won't make a appreciable difference unless you are very top of your game. I agree it's a diminishing return thing and I think at below 5ms we are probably very close to human limits already.
To me mechanical feel and ergonomics is a little more important once the latency becomes the bottle neck.
