Scores, of course.
Tracking times and deriving it from the time bonus goes along with a bunch of suggestions I didn't like in the past. One example from Sprint for SRB2: "Well, you can measure times in tics, then divide you end result by 35 to get a real time. It's more accurate that way." Another example from ks8 for Shuffle: "When tracking mini-games, you should have to subtract 10 from your end result because the game gives you 10 to start, and it should be based on what you earn."
I never really took to either of those ideas, because we've seen enough idiots struggle just to copy their times from their screen to the charts. Making them do math on top of that is a death sentence for TSC.
