Alan,
Well, you shamed me into actually setting it up and measuring the IRQ
delay. Amazingly, the delay varies from 25 to 110 milliseconds, depending
upon what type of triggering is involved. I did the test using their
lightning simulator and measuring the delay between the magnetic pulse

The AS3935 chip has a DSP on it that is doing a lot of statistical analysis.
It only draws a few microamps, so it's gotta be slow. I'd be VERY surprised
if the detection to output timing was even slightly deterministic.
It could be... It' s not hard to add nop's so that the detection always
takes the slowest possible time (but deterministic, or near).
