I was thinking of measuring the timings inside the Pi rather than the pulse
If you feed the same pulse to two pins, I'd expect to get readings of T and
T+x where the x is how long it takes to do some internal processing. If you
add a delay between the pulses, the internal processing will change.
These are my opinions. I hate spam.
