After you have added a few kata to a collection you and others can train on the kata contained within the collection.

This kata is definitely one of the harder 6 kyus, easily a 5 kyu (or 4kyu if it were pre-2017). Kind of disappointing (and surprising) that its satisfaction rating even got below 80%.
