Want to help analyze high speed data? Domino Data Entry (Patreon)

I've been trying to figure out domino velocities. Look... I know it sounds trivial but good grief it can get difficult. Slippage on the bottom, variation on if the domino hits near the top or the bottom, twisting during impact, etc. My first test was inconclusive because it seemed like the dominoes accelerated in the first 20 or so. Obviously the only reasonable answer to this is brute force empirical scientific data collection. I've recorded 19 high speed videos. Recording each individual domino impact down to the nearest 100 microseconds is a tedious task. If you have a few extra minutes would you be willing to pitch in and count some camera frames?
