I think the leaderboards need to introduce smaller increments of time to list the Tetris(NES) Runs in all categories.
Currently All tetris categories only count times to the full second. And in categories like the 300k category, this leads to many people being listed as having the same time as eachother. While in reality one of them is over half a second faster than the other.
This lead to Pixelandy Not getting listed as having the world record in the 300k Category after getting a Low 1:40. Because Joseph already had a high 1:40.
Maybe the best solution is to introduce only 1 extra digit instead of all 3 for milliseconds. but regardless, somethig needs to be done. Because I don't want to next person who beats my 300k WR time by 0.7 seconds to not get the recognition they deserve.
The first problem i have with a B-Type 9-5 category is that its limited to level 9 and to height 5. and thats such an arbitrary combination. because you can choose any level between 0-19 and height 0-5. So what makes the combination of 9-5 as speecial one? why speedrun that and not 10-5 or 15-3?
the Second problem which i think is bigger is that 9-5 is extremely easy for any good tetris player, to the point where its extremely boring. And you never want to have a category where the top players choose to ignore it because they can't be bothered to play it.
If i were to support a B-Type caategory, it would have to be B-Type on Any start. just clear 25 Lines as fast as possible. this allows players to play 9-5 if they want. and also pros to play 19-5 with rolling.
