It takes "some" time for the flash to actually fire...and I would also guess
different types of flashes have different timing (latency).  Does anyone
actually know what a typical flashes latency time is?

I can check my Elinchroms to see what they say this time is supposed to
be...as I have the service manuals for them, and they are pretty
comprehensive...hopefully, they'll have something to say about it.
