I seem to remember competing proposals, and have forgotten everything
about them; the cover letter also didn't have references to them or
mention them in any way.
As to the averaging and period, I personally prefer a PELT signal with
the windows lined up, if that really is too short a window, then a PELT
like signal with a natural multiple of the PELT period would make sense,
such that the windows still line up nicely.
Mixing different averaging methods and non-aligned windows just makes me
uncomfortable.
