How to Test Keyboard Latency in Five Repeatable Steps
A practical checklist: prep the desk, isolate the browser, sample keys, log jitter, then run a timed typing test to confirm feel matched the numbers.
Step 1: stabilize power and RF
Plug directly when testing wired boards; avoid mystery dongle chains.
For wireless, sit the receiver on the desk with clear line of sight.
After you change cables or receivers, resample latency before you judge a typing score from the same night. Fresh numbers prevent you from blaming technique for a flaky stack.
Close media-heavy background tabs before sampling; compositor contention shows up as spikes that look like keyboard problems.
Try the latency tester
Sample end-to-end delay in milliseconds inside the same browser you use for Type Faster. Log median and jitter after cable, receiver, or power changes—then rerun a timed test to see if rhythm calms down.

Close heavy tabs, pause media, and use a clean profile if extensions are suspect.
Collect at least a few dozen presses per configuration before declaring a winner.
Log median and jitter together; a stable median with rising jitter often predicts “off” sessions before your WPM chart moves.
Weekly retests beat obsessive daily retests. Measure when you change hardware, OS updates, or browser major versions.
Steps 4–5: log and benchmark
Write median, jitter, and sample count beside each change you made.
Finish with a Type Faster passage at a fixed difficulty to see if errors calmed down.
