Hi everyone, I'm a cuber from Japan (WCA: 2025TAKA04).
I built a small free tool called "PB or Fluke?" that answers a question I always had after competitions: was that result actually good for me, or just a lucky scramble?
How it works:
- Enter your WCA ID and upload your csTimer export file
- For each competition, it compares your official singles and averages with your practice solves from the 14 days before that competition
- Each result is rated (well above expectation / above / as expected / below / well below), with per-event scores, a radar chart, and trends over time
Everything runs in your browser — your practice data is never uploaded anywhere.
I've only tested it on myself and my son so far, so feedback and bug reports are very welcome.
