A) I really miss the yellow line in benchmark results table - it was
pretty obvious what the winning result is. Now it's just the green box
around ranking and that is hard to find. If the whole line was green,
that'd be different...

B) Wouldn't Twitter Bootstrap allow for sorting the table if I click on
the header? That way, I could sort the table by rank, average etc.

C) The "(winner)" text only appears in the "Winning score difference
summary chart". No other chart shows what the winner is, and that's too
bad. => Fixed on summary charts, but not on problem charts at the moment, because "winner" is ambiguous. It's clear though we want to "overall winner" there.
So we need a different term then winner.

D) Also, locating the winner visually among 20 or 30 lines is very hard.
What about drawing it differently? A thick line in line graphs and some
different filling in bar graphs?
