min | max | avg

I noticed 3000 occurrences where fmax is less than fmin. I excluded
these values to get the min difference between the two. Also, there are
20 "invalid"/"bogus" rows with negative values which were excluded from
the queries.
Thanks,
Tom

Can you show us min, max, and avg of fmax minus fmin? I'd like to
check my guess about that being a fairly narrow range.
