@Probably Intervert I didn't cover the height of a jump sadly, but these jump distances are how far you jump in each speed without interrupting the jump. You always jump this far, so it doesn't matter if it's one block high spikes or mini-spikes. However, two block high 3.6 spike jumps are not possible (I didn't really test the height of a jump, but I know that the height of a jump is the same for each speed and that it's a little over 2 blocks high).

For what it's worth, I will do some more math to find the height of a jump.
