COOP AP

ONLY USE IF YOU ARE PLAYING COOP

basically the strat is one person does normal prep while the other person goes and finds the first 8 strongholds. Finding them should take 20-30 minutes and all they need is an unbreaking elytra, efficiency diamond pick, 20 obsidian, ladders/pearls to get to nether roof, and about 20 eyes. They will not fill the portals they will only blind, measure eyes, and enter the ninbot coords into this program. Then they will press 'found' instead of lock. If a stronghold's portal has been filled (for example the one you beat the game with) you will press 'filled'. Most likely, the 1st and 8th strongholds will be 'filled' and the rest will be 'found'. The 8th one should be filled so that whoever is finding them can get back to spawn quickly.
I have no idea if this strat is the best but it's what i did so idk have fun
For the part after that unfortunately there is no good way to have a true coop mode (not with my skills at least) so both of you will have to launch the program separately. The person who found all the coords will press 'next', generating a backup file in the backups folder. they will send this file to the other person who will then have to MANUALLY enter each coord into their own program with the same found/filled buttons pressed as the first person (the 'use backups' button is greyed out because it will assume every portal is filled). Now that both runners have the same path, one of you will continue the one that is currently displayed and the other will have to press 'next' until it takes the path back to origin again and start from there. You will continue cycling through like this until you end up on the same path, at that point one of you will have to press 'next' until the last stronghold (129) and then work backwards. This will be annoying because the angles will be messed up and you won't have the optimal 'leave spawn behind' pathing.
