SensCalc
by SSH
SensCalc estimates a mouse sensitivity for sword PvP after a player records a few matches with a sword and checks the output.
What it does
Players run senscalc start to begin tracking, then fight a few rounds with a sword in PvP. When senscalc stop ends tracking, the mod reports which sensitivity value gave the most balanced mix of accuracy and speed. Per the author, more sword rounds produce a more reliable result, and the suggestion is a starting point rather than a fixed setting.
The mod is client-side only and runs on Fabric for 1.21.11, so the server needs nothing and players join without installing it. The author notes that it is in early development, and the logic for finding suggestions may change. Changing sensitivity based on its output may not improve aim, and the author states it will not fix poor aim, though it may make aiming easier.

Key features
Sword-based sensitivity estimate
Tracks sword attempts during PvP matches and calculates which mouse sensitivity fits the recorded hits and misses.
Start and stop commands
The senscalc start command enables tracking and senscalc stop ends it, after which results are shown from the rounds recorded.
Balanced result
The output favors the highest speed possible with a somewhat good accuracy balance, with an option to prefer the highest accuracy regardless of speed.
Simple setup
Two commands are enough to use the calculator, with no configuration screen to learn.

What the author says
Sensitivity Calculator is a simple mod that based on your misses when using a sword, attempts to calculate what you should change your Minecraft sensitivity to, which can possibly help you aim better. The more sword rounds you give it, the more accurate it should get.
