In Super Mario odyssey, there are people called 'Trickjumpers', which jump from one platform to another and they do it out of fun and to improve their skill at the game. They jump around by doing cap bounces, dives and other techniques.

There is a whole trickjumping community, which uses Discord servers to list trickjumps by their difficulty or more generally by their tier. For normal jumps, there are 5 tiers, which are called: Beginner, Intermediate, Advanced, Expert and Master. But there are more jumps, which are even harder and wouldn't even fit into the Master tier, so they listed in their own server: The Elite Server.

In the Elite server, there are four tiers: Low, Mid, High and Insanity. The Problem: Four tiers were good for the time when they created the elite server, but since people got better and trickjumps got harder and more precise, there needs to be another tier, which would be called God Tier, Extreme Tier or something similar to that. Insanity trickjumps these days range from 'Why is this Insanity?' to jumps that only one person ever completed with many others grinding it for hours upon hours. Examples for jumps which would be in the 10th tier are: Mummy Throw, Top Step, Pyrospike and some more. There are also many other jumps which would fit into the 10th tier, that are so hard, they are still unproven, like Vault City Reacher or True Spike Driver.

People already suggested a 10th tier for a few times, with many agreeing, but to this day, no 10th tier has been added. It would divide Insanity elites better, would be an ultimate goal, there would be 5 main tiers and 5 elite tiers, it wouldn't be hard to implement and how it seems like, there's nothing speaking against a 10th tier.
