Nice plugin, the interaction between estim and the scene is really fun (and possibly painful, haha)
As Boogaboo said, the 2B normalize the signal / smoothen it over time. So I set the smoothness at the minimum on the 2B (top right value on the lcd screen in stereo mode) to have the best direct response possible on the audio. Moreover, it looks like it does not register well at low frequency (1-2 Hz) so I put everything at 5Hz (among other things).
Also nice that the plugin - app protocol is simple, I can easily see it being used to write custom servers to control other toys (well, that's what I did just for fun anyway).
Regarding taking breaks I would recommend to have a look at LogicBricks. Using a StateMachine brick that sets different settings for a Loop brick which again triggers the animation. Check out the included Handjob demo to get the idea how to this would work. For non-coders it might be a bit tricky to understand at first, but you can setup all kinds of whip patterns and switch randomly between them so you don't know what the pattern will be :)
