ikegami,
I know that it is unlikely in this situation that there would be negative or even nil counts, but this code does the wrong thing in the following situation: 
ASDF 1 0
ASDF 1 -3

Specifically, it first sets the high water mark to 0 and then to -3. (Originally, I didn't have the group the same - corrected)

Cheers - L~R
