Spacebar sprint
Press Space as quickly as you can for 10 seconds. Repeated keydown events from holding the key are ignored, so the score comes from distinct presses.
10-second spacebar sprint
Distinct space presses count; held-key repeats do not.
Use the result as a baseline, not a diagnosis
BenchRush measures browser-visible input. If a result looks wrong, repeat the run, check focus and settings, compare another browser/device where practical, and use manufacturer diagnostics for hardware conclusions.
Questions people ask
Does holding Space increase the score?
