Subject: Re: Phase locking metronomes

Post:

If you take five metronomes and set the frequency, what is the probability that all five are truly at exactly the same frequency? I saw this and thought that the metronomes were trying to drift from the forced coupled frequency.
It would be interesting to set all five away from the cans, record the "tocks" and see what variation there may be in the frequency, then to do the same on the cans.

Nope... that's a different effect than the can motion. It takes place over a few dozen cycles.
