> I've taught 5 kids to ride bikes this year. The method is quite simple and takes only a few minutes and some light jogging behind them.

You need to compare this against the base method as a control (see above for my anecdote using my own kid).

The control method (i.e. do nothing other than scoot around) is about 5m. Maybe 10m at most. I don't know what I'd be saving if I got that number lower using props like a rope (or the sheet mentioned by a sibling).
