About this Mod
Sens Calc
AKA Sensitivity Calculator
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.
The mod is simple to use. There are a set of commands to use to enable the mod and get your results:
- /senscalc start (enables tracking)
- /senscalc results (after using /senscalc start and doing a few matches of sword will show you the results, with a balanced sensitivity which is most recommended for a mix of accuracy with speed, highest speed possible which attempts to find a high speed but somewhat good accuracy balance, and best accuracy which tries to find the highest accuracy no matter how slow it is.)
- /senscalc stop (use after /senscalc start to stop tracking and stop the calculator)
Please note that this mod is early in development, its logic for finding sensitivity suggestions may be off, and changing your sensitivity to what it suggests won’t magically fix your horrible aim, just possibly improve it or make it easier to improve.

SensCalc server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is SensCalc compatible with fabric?
SensCalc officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with SensCalc – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SensCalc consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
