Which country voted the best at Eurovision?

Eurovision was on yesterday. I’ve never been interested much in the musical side but the weird political dynamics of Eurovision voting have always fascinated me; I tune in each year just for them and somewhat snarky commentary of Graham Norton, the UK commentator.
As I was watching the jury votes come in, a question popped into my head: Which country has voted the best in Eurovision? That is, which country was best at picking the eventual top 10 and in the right order?
Strangely enough, while there’s plenty of work on voting blocs and bilateral biases at Eurovision, most of it asks who votes for whom; I wanted to ask who votes accurately. I couldn’t find anyone asking the question that way, so I decided to do some data analysis myself.
The metric To begin to answer this question, I first needed to formalize what “best” even means. That is, some mathematical notion of “good” and “bad”.
