Non-timing "Blinky" ESC Test Using an Oscilloscope

I helped Chuck when he tried one of these, but there was no control for horizontal position, which is absolutely vital to the delay measurement. It seems like the person who wrote the software has never really used an oscilloscope. Does the open source software include a horizontal position control?

So far I've tested 3 different ESC's in blinky mode and getting repeatable results. With one degree of boost on a Tekin RS Pro, it's an obvious fail (cue Tekin jokes).
Lots more testing to go and work to do on case/UI, plus explore some closely related uses. Might yet go down in flames, but so far looks promising.

Timing
Very cool. I saw an older YouTube video were a guy is checking a hw vs novak. He found timing in hw esc? (Hw cheater esc helped put nail in novak coffin). J/k. I do not have the facts..Maybe start a list of tested models and update. Just very interesting. At a local level nobody checks rotors, timing or voltage. https://youtu.be/DW5VSubCE6E. 7:30 mark.

I've done early testing on 3 ESCs at the moment. A Tekin RS Pro Black Edition, a HW XR10 Pro Stock Spec and a HW V3 120A. The Tekin and the V3 are almost bang on 0 degrees, the XR10 has a very, *very* small amount of what could be considered negative timing, but still fixed. They all easily conform to my understanding of the requirements for a blinky ESC.
I need to do a better job of documenting firmware releases etc, but these differences (as observed above) on their own will not constitute any performance difference on the track. Maybe it's hackneyed, but on circuit, I found the Tekin to be quite binary in feel with excellent brakes (sometimes too strong, so often dialed back). The V3 was smooth but lacked good brakes in higher-turn spec classes. The XR10 is in my current ride and has good feel and brakes. I have a Muchmore Fleta in another car, but no motor, so haven't tested yet. FWIW, it has a very similar feel to the XR10 in my experience. I only bought the XR10 to test some other stuff and had no reason to change it out.
For those familiar with the 'scope testing method above, would a "go/no-go" indicator work best, or would people want to know the actual delta time between sensor and motor?
