I think it would be nice to do a category 10 line. It's not that complicated, so everyone can speed it. If I try to make a video
The 100 lines and 300k points caregories aren't too long and provide a good measurement of players' skills.
A 10 lines speedrun would only last about 30 seconds or so. Assuming you would start timer on level select(like the other categories) this would not be a good run to improve your Tetris skills as it's far too short to get any quality time with the game.
If we are going for lines, I don't see any reason for a category under 100 lines. Even on level 0 start there are over 200 people on the board with times under 10 minutes so it's not a lengthy speedrun.
It would be great to get more people involved in Tetris but removing the need for a level of skill isn't the way to do it. Learning how to get to 100 lines really isn't that difficult.
Maybe if there was a meme category page for Tetris, there are not enough ideas to make that a worthwhile thing, though.
