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.

The description fails to specify that the result is to be capped off (rounded down) rather than rounded or kept as a floating number.
