I've added the game with the base modes as categories: https://www.speedrun.com/tetrispsp I think Marathon (level 1-15) is the best category for this. 10,000 points is simply too short for any meaningful competition. I also added the variant modes as Sprint subcategories, since the common denominator is that they all have as a goal to clear 40 lines.

I don't think it's necessary to add any more categories, although I suppose I would be open for something like 100,000 points or clearing Marathon from level 15 as a shorter category.
