ALP Sensor group firing question. ( Rear Set-Front Set)

Interesting, and this feeds into my speculation on the cable length thing, that the software calculates the time of arrival on each head, and, after calculating the proper counter pulse, it fires each head with appropriate nanosecond offsets, so that gun sees all of the returns in a synchronous manner.

Now you have got me thinking, one or possibly two of my cables in my rear setup was/will need to have the extension options fitted, do I need to have all three cables in the same group in the same length?

According to Tom, this is not the case. Makes sense that the software handles any delta derived from mismatched cable lengths. I assume the CPU 'collects' the time stamps of off-to-on transition of a pulse for each head separately and measures the delta, if any, on reception.
