For all contestants whose score was >75%, identify who had the greatest percentage of Hate votes. Repeat for lower thresholds.

If this is what you want, understand that the same contestant could "win" at more than one threshold (ie I checked - S9 Eliza has the highest hate vote percentage at both the 75% threshold, and the 70% threshold).

That's pretty much it.

Might as well give fresh names for each theshold. If you give Eliza's percentage of hate votes it will be clear she would have won for lower thesholds too. If 2-3 people are exceptionally hated at a theshold, list them all. Use your discretion so all noteworthy cases appear. For example, if 3 people between 60-65 are more hated than anyone between 55-60, that is noteworthy.

Then repeat for most loved people below certain thesholds.
