Prac Fix
by Diabet
Prac Fix corrects inaccurate practice positions on parkour servers for Minecraft 1.8.9 with Forge.
What it does
On parkour servers, practice positions can be saved at the wrong place, because the server sometimes updates a position after a player has already moved on. The mod changes how the client reads that position so the saved spot matches where the player actually stands.
Key features
Corrected practice positions
Practice positions saved on a parkour server are read more accurately, so restarts land where the player intended.
Movement tolerance check
A position is treated as stable when the player moves less than 0.03 blocks in the last tick before stopping.
Optional debug messages
A debug message can show when a position update happens, which helps when checking the timing of a practice run.

What the author says
This means that if you move less than 0.03 blocks in your last tick before stopping, your server position won't be updated for another 20 ticks. If you prac during this time, your prac position will be inaccurate. Normally, you would either jump to force a position update or wait the 20 ticks before running /prac.
