An example I can use is Hades Ex, and the frequent checks the fight involves. If we as a group are able to burst him down to 3% hp in 1st phase in relatively short order without any echo or other benefits, we know our checks are on point, as is our rotations. We also communicate damage windows, etc to help. Eventually, you run with the same people enough, it kind of becomes second nature.
I see one major flaw with this method. How can you use this to improve your own personal performance? Hitting different HP thresholds can be a result of so many different factors, I'd call it near impossible to track on a pull by pull basis. Maybe one of the DPS got a bunch of lucky crits? Maybe another messed up their rotation causing you to be slow? Maybe someone stood in a circle so healers are doing less DPS because they need to heal or rez? Whereas with a parse you can see clear as day "I did X damage" and not only that, there's another tool that will further analyze it and tell you "You could've used this skill 6 times but only used it 5" or "You clipped your GCD here, here, and here"

I feel the only way to get as much information without a parse would be to record every fight, and review them personally on a second by second basis. Which monumentally more work then just looking at the numbers + above tool.
