I do get it that clear is good.
Some people measure and some people calculate.
I am the former type. I also feel my way to performance and without
measurements I can't feel enough.
I don't know how to measure clear.
Video will help but that's not enough.
If you're worried about the difference between "perfect combustion"
and some subtle variation therefrom, you are deep in "performance
anxiety leads to premature optimization" territory (IMHO).
Especially with a peroxide motor, the best Isp comes fairly near
stoichiometric conditions, and the optimum is rather broad...
(LOX motors tend to have more of a "sweet spot" related to being
"just the right amount" fuel-rich.)
