ahh, not I understand. collectl always reports memory metrics in K. in
brief mode you get 3 digits and in verbose mode you get 6 so if you exceed
the number of digits collectl divides by 1024 and stick on a K, M or G
depending on how many times it has to divide to get results to fit in the
allotted space. in the case of plot mode as you've shown about you ALWAYS
get the full numbers in K.
as for not matching, remember that going from K to M to G, you're dividing
by 1024 and not 1000 so the numbers in plot mode wouldn't match. maybe
that's part of the confusion.
