  Geez, do I feel dumb. Of course you're right, I'm not at all sure
what I was thinking, you have to clear the accumulator after the 256th
sample for the method I described to work... The bad thing is that now
I cannot remember how I wrote that averaging routine at work last week
-- I'd better check it Monday.

  Thanks for straightening me out guys.
