Sorry for the confusion guys. I was misinformed about what I was
looking for in the table. Given the same type of data:

1 - 239.21
2 - 239.55
3 - 240.30
4 - 0.35
5 - 0.44
6 - 0.53
7 - 1.20
8 - 2.40
9 - 0.25

I need to know how many rows before the following row is less than the
previous (in this example, a total of 5). I'm trying to find the number
of entries (could be days, weeks) before a computer is reset, and SUM
them for a total number of occurences (days, weeks, whatever). So for
this I'd sum rows 1,2,3,7,8 for a total of 5.
Does this help?

Thanks again.
