Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

This seems super complicated for 7 kyu.

That test-case where 13 is a "Balanced" number should be better explained and an example with a 2-digit number added to description imo.
I notice a pattern on here where a lot of beginner katas (7kyu etc) are becoming near-untouchable for someone actually at that level, people complain about it, only to be countered by a bunch of 1 Kyu & 1 Dan folks with "it's actually correct to be 7kyu because... ==> <proceeds to list a bunch of concepts that are a solid 8-12 months away for someone who's actually 7 kyu>."
Even the author of this kata (see below) has estimated it to be at 4 Kyu FFS.
This would be 7 kyu if it didn't have the performance constraint.
If you're at 2 Dan with 3000 Katas solved, I'm sure.
But this is marked 7 kyu, which is absurd.
But... but why!?!
Jesus Christ.
