The Rules state:

Calculator functionality more advanced than you'd find on any given 4 function calculator is banned from use in speedruns; I.E using an external tool to locate the stronghold.

I saw Couriways 4th place run on 1.16.1 RSG. He asked chat to figure out the divine travel coordinates.

I know he could just look up the coordinates himselves or memorize them.

I´m just curious if there are any rules that regulate how much or wich external helps are ok or not?
