So you're telling me..

it could have to do with the fact that the "nice green parse" was 47% nowadays, wheres it was a 95% parse back when it was recorded. theres a pretty hefty difference between checking the historic logs or the numbers in the fight logs.

Are you sure it works like that?
I thought the actual parse percentile was saved forever as that same percentile you got it when it was uploaded and recorded, the only thing that updated was the median.
At least for warcraftlogs I can go back and see all my 100th and 99ths from 4 wow expansions ago (when warcraftlogs released mid mop expansion) even if someone beat it I still got the 100 recorded historically unchanged for all to see.
I can also go back and check ultimates done in shb and they are still the same percentile.
Now maybe fflogs is different but I doubt the creator would be changing shit around for no reason between the almost identical pages.
So unless I did miss something about fflogs that is a real green back then.
