Why don't you just run by following the existing rules ? I don't know what's wrong or what's complicated in them And please sometimes, be more specific, I think you are mixing everything up

14. In-Game timing can be done either manually or using the version of MinecraftTimer that matches the Minecraft version used. Download links provided in the "Resources" section of this website.

Yet the two results may have difference more than 50%. Still allowing both is unfair

I still can't make sense of your sentence. I would suggest an advanced English course.

I think the first paragraph may be harder to understand. If you don't understand it, maybe you should ask AwesomeCuber.

IGT can be done either manually or by using the auto-timer. If there's a difference, allowing both is bad.

I have not seen yet any signs or proof that such a difference exists.

If a command can be used without cheat, is it allowed in a map run?

How come nobody ever runs in 1.9?

It's a slower version for Any% runs because the dragon takes longer to kill.

I think a 1.9+ category would be fair. Its hard and could be intresting. I saw already a speedrun on YT in 1.9

If unintended glitches happened, is the glitchless run just broken? When I was using win7, Java usually crashes and make dup/clear

If an unintended dupe happened that would make the Glitchless run invalid.

what about an unintended item loose?

If it cleared an item instead of duped it I don't think we would deny that run.

Is there an all achievements category ? if yes where i can't find it

It's under miscellaneous on the full game page

Or just on the full game page

oh well guess i was blind thx anyway ^^

no worries =]
