@Mag40 - I found the source clip, but the frame rate is only 10 FPS... not 24. And the peak is reached by 0.9 seconds, not 1.24 seconds, thus making the gravity be 3 m/s^2, not 1.62. This could be achieved by 44% slowdown to 56%.
I have no idea where this video gets the idea for a 66% slowdown, nor realizes that the slowdown done for this scene should have just been for the kick... it's not all-or-nothing, using an optical printer.
Plus there are two more issues with this scene:
1. There is evidence of atmosphere by the trailing dust cloud, which happens in atmosphere as the lightest particles get left behind.
2. There is a Clunk sound that happens, which seems like another mistake where sounds from outside the space suit are being picked up by the mic.
Here's the clip I watched, and saved to frames: (starts at 2:32)

This isn't a great example to make proofs from, given that it's dust cloud, so harder to determine "peak of parabola" plus it doesn't show the other half of the parabola, so that we can determine if it's a perfect parabola, vs. one hindered by air resistance.
