I recorded at 120 fps with a samsung galaxy S6, then went back and counted frames for each grabber to try to get accurate speeds. Because of the fact that 120fps recording gives me a time resolution of 8.3ms I rounded times to the closest 10 or 5 ms increments so times aren't perfectly accurate. The other thing to note is that I didn't have a way to know exact enable times for matches that we (1678) didn't play in so I don't know exactly how long grabbers took to startup. Our triggers took about 2 frames (~15ms) to fire when tested off the field so that was the only robot I had an accurate initialization time for. All times for recorded grabbers are posted below.

In no particular order:

1114 harpoons - 105 milliseconds (word of mouth)
1114 2 can - 350 ms
971/254/973 cheesecake - 175 ms
148/1923 cheesecake - 175 ms
1678 (4 wraps, on the field) - 175 ms
1678 (5 wraps, pits) - 158 ms
987 - 290 ms
3310 - 205 ms
5027 - 266 ms
2056 - 250 ms
3940 - 300 ms
1918 - 225 ms
1711 - 370 ms
330 - 400 ms
2046 - 350 ms
3339 - 470 ms
368 - 370 ms
1983 - 480 ms
166 - 400 ms

I accidentally deleted some videos but I think I recall a couple of times for some teams I recorded, give me a heads up if I made any mistakes:

67 - 205 ms
548 - 205 ms
16 - 350 ms?

Thanks Jake - excellent data!
Are the original videos available anywhere?
