It's not really clear what you mean by "disintegrate" - but certainly they don't tie up with what happens if you look at the "reputation by time" part of the user accounts.
I have a sneaking suspicion this may be due to questions being undeleted: so when compared with a snapshot of reputation taken (say) on Sunday at midnight, Michael Stum may indeed have over 8K more reputation than he did before... but most of that reputation was actually earned before Sunday... it's just that it popped back into existence after being deleted.
Alternatively, it's just a nasty bug somewhere which has no particular way of squinting at it to make sense ;)
