Speedrun Split Variance Calculator | Plan Smarter Runs

How it helps

Use it for a focused task

Speedrunners often stare at split data wondering why a PB run fell apart. This calculator helps you compare splits from two different attempts side by side.

You can see exactly where you gained or lost time, how consistent each segment is, and which splits swing the most. It works entirely in your browser.

No account, no upload, no data leaves your machine. Start with one of the preset game examples or type your own split names and times.
