so for this one, I read the wiki and it says that performing Kata at different levels gives you different amounts of honor depending on what rank you're currently at

"When a kata is completed, you always received a set amount of honor points based on the level of the kata as well as an internal score that counts toward your next rank. Since every rank requires a higher score than the last, Completing an easy kata well below your current rank will result in little progress. However completing a hard kata above your current rank will give you much more progress towards leveling up. As such, completing a lot of low level katas will give you a lot of honor, but will not increase your rank very quickly. Completing more hard katas will level your rank faster."
