I believe you, I just wanted to understand it. It is hard to argue with empiracle evidence
So we need to make sure that we are not double counting injector pulses before we subtract 500uS per pulse.

The oscilloscope is to make sure we are not cooking the atmega. Though a graduated cylinder might be handy.
ttoyoda, the thought is that we take many many many readings while in the wait part of the main loop and only look at the max value we collect. and if we are at 1024 then we know for sure we are at or beyond the limit at some point during operations. Not that we will detect every peak and its absolute value that reach our $3.00 chip.
