Yeah, I would agree with both of you, if a run is in 3 worlds then really it should be 3 runs, the all bosses record should really have to fight the bosses consecutively in the same world.

Player data transfering is only used when set seed so you can use good of different known map. Three category all have set seed glitch submission, and there time sum is a lot less than the allboss set seed glitch run. There seems nothing much to reuse, thus requiring in one world is okay
or just because you can collect blaze rod and wither skull at the same time and kill the wither with the end-to-overworld portal it can be faster?

By the power of RNG anything could be faster on one world.

I see your point (I think) if you can prove that you don't edit Minecraft when doing all bosses I reckon you'd be OK set seed with glitches the other categories probably not as much

Where can i find the current leaderboards of Custom Maps?

Right here

What do you think about Dinnerbone's How Did We Get Here challenge as a speedrun category?

Important speedrun question: why does it take over 48 hours to verify our run

Because the mods are very busy with life

ok I mixed modification and moderator ...

Are touchscreen allowed? Seems give good when turning head and moving items

since technically every platform that has minecraft is supported I would say yes touchscreens are allowed, Its like using a classic controller for a wii game (sorta)

For all bosses, is it okay to just stuck the wither in the bedrock and leave(there'd be some time the chunk keep active), or it needs to be seen killed?

I would of thought as long as you can prove that you didn't jumpcut the video or change outside code this would be fine, I am not sure tho

Just you can't prove the wither is killed before you kill the elder guardian

l4m2 the question guy ^^
Just try a run and see if the mods are accepting some potential new strats 😉

http://www.speedrun.com/run/6yjlq1nz used optifine.zoom but accepted. Is it just okay if the zooming doesn't give any good?

I would assume that since its a set seed run it doesn't matter

Set seed doesn't mean set RNG, the mob spawning can still vary

Timer mod and optimize(don't affect the game at all) mod always allowed?

yes
