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! :)
