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.
Get started now by creating a new collection.
Unfortunately, there is no preloaded object in PHP, you have to make it yourself.
Ranks of katas can't be changed. And the criterias for kyus changed with times. Old katas tend to be overranked, for others it's the contrary. You should not care about a kata being overrranked or underranked by 1 kyu, it's not meaningful in general.
Yeah, I just came to comment the same.
