Like if I'm doing axis calculated am I allowed to use a calculator to make things faster?

Yes, you are. The mod team unbanned them a while ago, so now you can use calculators to get exact positions of strongholds. The resources page has two calculators: the ContariaCalc for pre-1.9, and the Ninjabrain Bot for 1.9-1.15 and 1.16+. You can access the resource page here: https://www.speedrun.com/mc/resources

Ok Thanks
