I know, he just made a a tool to switch something inside the transmitter and measure when the change comes up on the channel. I think some bad results will be better when doing it on the track and not at home where many wifi signals are in the air. But he is reading a total latency caused by everything between transmitter control to the servo channel output, it is very variable and can go beyond 10 msec of time, that is huge. That is the difference between hitting the Apex right up to launched by the curbs.
