Inspect keydown-to-keyup timing reported by the browser; results include human hold time and browser scheduling.
Tap and release a key repeatedly, then compare your own hold-duration results on the same device and browser.
Try to keep both your holds and gaps even at a comfortable pace. This series uses one fixed key. Hold is keydown → keyup; release gap is the previous keyup → next keydown. These are human input timings observed by the browser, not switch latency or debounce measurements.
0/20 · Select one key, then start a 20-tap series.
Hold: N/A
Release: N/A
For this site’s normal-gravity wave, longer holds relative to gaps move the path upward; Mini magnifies the slope. If mean hold and gap are similar but SD differs, work on the less stable half. The first tap has no preceding release sample.
Result guide
The result is the elapsed time between the browser receiving keydown and keyup for a press. In practice, that includes how long you physically hold the key plus browser scheduling.
For Geometry Dash wave practice, shorter or more repeatable holds can matter when you are learning press-and-release rhythm. Compare your own repeated presses rather than treating the number as a keyboard ranking.
This is not a true hardware-latency benchmark because there is no external clock marking the physical instant the switch actuates. It should be described as browser-observed key timing, not input-lag certification.
