Bit of an error creeps up when you are in cow loon, events don't seem to consider your "Actual" max and just look at the default max before throwing a game over when you pass it (Max was closer to 80 but the game over was thrown when rear was 63)
This is actually present in all special forms but BASE A rank. I think all the special forms are looking at the base fullness and not counting any points in fullness
