Comment (by madscientist159):

 I need to run a full calibration, because the actual delay through the
 system is some formula of (n / fps) + fixed_delay, where I don't (yet)
 know exact values of fixed_delay, but the number of frames is definitely
 somewhere between 3 and 6 inclusive.  Given the hardware, I suspect it's
 either 3 or 4, but a setting 5 frames with a 50ms fixed delay has been
 working reasonably OK so far.

 I still have to build a bit of custom equipment to try to accurately
 measure the delay before I can tune further.  Homebrew equipment can be
 all kinds of fun! :)
