When someone gets into speedrunning for the very first time they know it'll be a while before they have even a shadow of a chance at a worthy time. You know, like me lol. I just want an easy timer I can have in-game so I can practice until I get a sub-45 time for 1.16. Unless I get sub-45 or so I won't even consider trying to stream or submit anything because if I can't even get sub 45 it means I haven't gotten used to the speedrun techniques yet. For now, just to practice as a beginner, this will do nicely. ;) Only issue maybe is you have to put the datapack in each world because that's how datapacks are, so it's a little inconvenient for jumping through a lot of worlds trying to get a good random. But for practice doing a few set seeds is fine too anyway.

Yeah it's meant for people who just want to try a speedrun without it being too serious, otherwise I would just recommend using a separate tool for timing. I'm pretty sure the timer pauses if a dimension is loading, so you shouldn't use it to keep track of the exact time.
