Hi Pall,
Which help patches? I haven't seen a single help patch that substitutes
strings of [+~] to double the incoming signal where a simple multiplication
would do.
I have seen cascades of [+~] for additive synthesis, but that's not the same.

Ah... I've seen this in some of the help patches. Why would someone do it with
multiple [+~] instead of a single [*~]? There's no difference?
