for some unusual reason I feel like 4* is a incredibly strange difficulty. The difficulty jump is strange, and I've even heard of people skipping directly from 3* to 5*, and I know the star system is flawed in one way or another but the health drain going from 3* to 4* in a way is drastic enough that they feel like completely different difficulties, either the health drain is so bad that missing a single note requires combo bonus to get the health back, leading to situations where the player is playing the entire song within the "danger zone", or it drops ~30 - 50% when missing a single slider and while there is a transitional difficulty for these difficulty's generic names, not many people seem to use it so I end up struggling a lot on 4* despite being able to easily get a FC on 80% of 3* with some effort.
I know most of the 4* patterns pretty well and can even flawlessly execute them but when it comes to actually beating a song, either me not being able to keep up either through me just not paying much attention where I've been playing for so long or there is a unique pattern that appears in barely any songs just completely walls me off from about 50%, not to mention the times where the health drain is so bad that because I can't nearly FC 4* means that I physically cannot keep my health up
