Rolken's going to need a lot of help setting up the new competitions within the next week. I'll try to help out with StH. *Spoliers Ahead, mostly designed to help out and to get people excited about competing in this game*
-The way the stage paths are formed, there are 4 stages on the top and bottom rows, 6 on the upper/lower middle rows, and 7 on the middle row, giving a total of 27 stages. The final level of each row, the other 3 stages on the top/bottom rows, and the 1st stage of the upper/lower middle rows will only have a hero and a dark mission. The rest will also have a neutral path. This gives a total of about 68 things to time attack in, give or take a few if my calculations are off. This doesn't include the boss battles, although it has been confirmed that some bosses will be fought more than once. However, the terrain and tactics change depending on what stage you fight the boss in question at. IMO, the tables should be organized from left to right, then from top to bottom, then by the alignment of the mission in that respective stage.
-I just preordered this game today. For an additional $5 fee, my copy (gamecube version) comes with a StH ski cap.
