Anyhow, who cares how long it takes to go from A to B, as that fact would only be to determine the rpm.
as long as one sees it hit the far horizon and then trigger, thats the start for the delay, the crank is still at the same point in degrees.
Then you or someone nice enough to change the program for you would have to do it. I made the information available in previous posts and a little bit here, I'm not about to totally rehash the subject. But if someone is going to use a hall-effect then they must or should understand polarities, hall-effects, rpm, MCUís, and how it all inter-relates. As far as rpm, Jake spent a lot of time converting rpm to milli-seconds and even micro-seconds to get the timing right in the code. (Counting Clocks) RPM and time even determines the components you can use for the circuitry, in an ignition time is everything.
I have attached 2 PDFs for further reading if anyone cares.

The point was, you kept insisting the effect of the hall had an inevitable effect no matter what, wheras I maintain it is in the way the program is written.
