When attempting to utilize the documentation in: https://github.com/lucko/LuckPerms/wiki/Argument-based-command-permissions#promote-other-players-but-not-to-or-past-their-own-level-on-a-track

If the permissions listed are given in a server context to a group (G1), the functionality is backwards of what is listed in the documentation. Instead of having to specify the groups G1 cannot promote to or beyond, I have to add permissions for the groups that G1 can promote with the context.

In this case: the group btccraft-admin can promote a default user to the rank btccraft-helper, but only because of the permission: luckperms.user.promote.btccraft-staff.btccraft-helper server=btccraft

Without that perm specified (like the documentation directs) the group btccraft-admin cannot promote a default user to btccraft-helper

Verbose log, with example of promoting within limits and trying to promote past: https://luckperms.net/verbose/#aOR4qcVkjx

I believe the documentation has now been corrected - you need to get the permissions to false for the groups you don't want them to promote past.
