It's a really interesting video and I enjoyed it -- thank you. A nagging request would be the use of SI units throughout, but I suspect that is an en-us translation issue ;-). [For example, for others, 210 feet per second is about 64 m/s]

Something I might like to cheekily request -- at some point, the difference between v^2 = u^2 + 2as and what you observe will become really quite significant, and I suspect the Magnus effect on both the airsoft pellet will be quite significant. Could you do Schrilen photography and illustrate the air pressure changes at the same time relatively easily with your setup?
