It looks like the time it takes to go from .7 to .6 is significantly faster than it takes to go from .6 to .5 (and onwards). In other words, it seems like at the .6 second mark, the slowmo slows down slightly.

It's by no means scientific, but by using the cadence of the first speed, I counted that it took slightly over .8 seconds to get the shot off. The ball was still in his hand when I counted .8, but the ball was out of his hands by the time I counted to .9. I don't know what the previous play was, but I'm curious if they were as "careful and meticulous" about adding the right amount of time to the clock prior to the play as they were in re-calculating how long it took him to shoot. Also, since the game clock only shows one decimal spot, is it possible there were additional hundredths of a second that were unaccounted for? In other words, could the actual time on the clock have been closer to 0.89 seconds, but because it just shows one decimal you don't know about those extra hundredths of a second? I don't know all the rules of timing; however, if that's possible, then I feel like 0.9 seconds should be the threshold to measure against, and he definitely got it off by then (it seems he got it off in around 0.85 seconds).

By using the cadence of the second speed, I counted that he got the shot off in 0.6 seconds, way below the time left.

In no way did I get anywhere close to the 1.2 to 1.3 seconds that the MWC official statement cited. Which is why I still think, if they're that off, that their methodology wasn't sound and they should have left the basket stand.
