That means any edits should be considered entered at the time of the most recent edit.
Ah, but then I could flip-flop my comment # with someone else's, by waiting until they comment after me, then editing my comment to be after theirs.
What a tangled web we weave ...
The other way we could play it is consider all edits as invalid.
I made a little amendment that will work even though there is still a tiny loophole. I will check the comments at one time when I see 51 valid comments. I will record the time the comments are checked.
