Downgraded Best Perf. Avg?

Last night I was proud of myself and sitting on 4 99 overall parses and 4 100 for ilvl parses and then this morning they were updated and now my overall is 95 and ilvl is like in the 80s. I understand that more logs were probably uploaded but I was under the impression that the 'Best" stayed even if your ranking is usurped.

I’ve had it not show an ilvl parse before because there were not enough people to have a reading but these had a lot of parses and showed me an avg.
