Is this explained elsewhere (like, officially)? I checked around a few times, but I couldn't find anything.

Qualified = count(opinions) >= 10
compscore = sum(avg(nonNULL(opinion.category))/count(avg(nonNULL(opinion.category)) except Overall and Re-view
Note: The top and bottom 10% scores are removed from the average calculation (also known as the "Olympic Average")
score = Bayesian Average(avg(compscore+overall+review))
Bayesian Average = (v ÷ (v + m)) × R + (m ÷ (v + m)) × C
where:
R = average for the video (mean) = (old score)
v = number of votes for the video = (votes)
m = minimum votes required to be listed in the top 10% (10)
C = the mean score across all videos (average all vids)

You don't mean these equations, do you? (copied from Top 10% Rated Videos page)Qualified = count(opinions) >= 10
compscore = sum(avg(nonNULL(opinion.category))/count(avg(nonNULL(opinion.category)) except Overall and Re-view
Note: The top and bottom 10% scores are removed from the average calculation (also known as the "Olympic Average")
score = Bayesian Average(avg(compscore+overall+review))

v = number of votes for the video = (votes)
m = minimum votes required to be listed in the top 10% (10)
C = the mean score across all videos (average all vids)
The scores on the top 10% list go up to 10, but the numbers under "Avg (score)" in the star ratings field never exceed 5, so they can't be the same (unless you're supposed to divide one by 2 to get the other). Am I looking in the wrong place?
