Ok, I can't really pixelscale the movement, because we don't see it. But I can calc it. Looking at this
scan, I can see that the movement is a bit above 90 degree, but below 180. I think that ~110 degree works.
Using this
calculator to find the length of the movement, considering an arm of c
meters, I get 0.332086m of movement.
The calculation I sent above got a distance of 0.011m between her and the bullet, so I'm gonna use the speed you gave me, 220 m/s.
Time: 0.011/220 = 0.00005 seconds.
Speed: 0.332086/0.00005 = 6641.72 m/s, Mach 19.363, High Hypersonic.
