This weekend I wrote a simple webpage to measure the accuracy of my rhythm (the timing project on GitHub). Just load the page then start tapping any key(s) periodically; the page records and reports on the time between key-presses.
In playing with the page my standard deviation normally hovered around 20ms, drifting up towards 40ms. This was without a metronome.
- What is a good accuracy?
- How long should a rhythm test last? Five seconds seems too short and five minutes seems too long.
- Am I reporting the proper statistics?
- How can the app be improved?
How’s your accuracy? Got any ideas? Please let me know!
