Yeah, but shouldn't a delta of 1/3s be the same as 3fps? But the 1/3s to the left does not look like the 3fps to the right.

And it does say that the picture to the right is just like in Quake. So I was guessing that maybe the one to the left is not. Like, it has higher initial velocity and max height, and longer time spent in the air. Like the picture to the right is a jump that lasts for <1s while the one to the left is a way longer one.

Would be nice to have like axes with labels and things on them.
