 * Slowness
 * Jump Boost

Speed
Speed increases the player's ground speed, making them move 20% faster per level of speed.

Speed does not affect movement while airborne, therefore sprint-jumping becomes less efficient the higher the level of speed (for Speed II, it is generally slower to sprint-jump than to simply run)

The speed is presented in meters per tick (m/t). To get the speed in m/s, simply multiply by 20.

To get the max ground speed with 45° Strafe, divide by 0.98.

Slowness
Slowness slows the player's ground speed, making them move 15% slower per level of slowness.

Slowness does not change movement while airborne, therefore sprint-jumping is more efficient.

The speed is presented in meters per tick (m/t). To get the speed in m/s, simply multiply by 20.

To get the max ground speed with 45° Strafe, divide by 0.98

Note: past level 7 (VII), Slowness completely stops the player in place.

Speed and Slowness Interaction
Speed and Slowness multipliers do not add, but rather multiply.

For example, if the player has Speed III (+60%) and Slowness IV (-60%), the resulting speed effect is not +0% as one could expect, but -34%.

Jump Boost
Jumping sets the player's vertical speed to 0.42 by default.

The jump boost effect increases this initial vertical boost by 0.1 per level.

Here is a list of the max height the player can reach for various speed levels. Notes:


 * In 1.9+, the default jump height is increased to 1.252m, but that does not change the jump height with jump boost in general (see Movement Formulas).


 * Past level 129, Jump Boost becomes negative, which makes the player unable to jump (unless they use the negative speed to bounce on a slime block).


 * Levels 252 - 256, the player is able to jump again, but with reduced jump height. Level 256 has the same jump height as the default.
