Someone (can't find thread now) was talking about wanting a tap tempo that kept all the human failings. I thought it was a good idea so I sat down and had a go at knocking one out - here it is.
It takes 9 taps (yielding 8 durations, so superficially it's tied to 2 repeating bars of beats in 4/4 though of course given that you can tap out any rhythm in those 8 beasts, you can feed it any meter you like). Also it's scaleable. I nicked hardoff's toggle because I thought it was pretty.

You could probably "improve" it by resetting the metro counter on tap 8 (so that the metro immediately goes into your sequence as you finish. That's probably a matter of taste though.
