Would be nice to throw 3laps into the time trials leaderboard since you get your time at the end of the race. (Although the fact that the game saves only your best laps is kinda weird and funny)

Also the cup runs would be a nice additions. (ie. Easy, Medium, and Hard). I know some runs of these have been done before. Seems like some people did RTA and dugongue just did IGT only. Seems like RTA might be the better option for those as the main column, but in game time could be added as an extra field too.

Happy to help with or discuss any of this :)
