Human Precision updates inside the browser and depends on your display to show each new frame. A monitor that refreshes more frequently can present visual changes at shorter intervals than a lower-refresh display.
Refresh rate is not the whole latency chain
Panel response, rendering time, browser scheduling, input polling, operating-system processing, and game frame rate also matter. A high refresh-rate label does not guarantee identical end-to-end latency between systems.

If you change monitors, treat the new setup as a new baseline. The leaderboard does not attempt to mathematically normalize every possible display.
