Levels 32 through 255 can only be reached on B-Type. After level 31, the pieces drop slower. After level 71, the speed fluctuates. After level 255, takes you back to level 0. Nintendo never expects you to make it that far as levels 29, 30, and 31 are impossible for an average human skill at height 5. Only TASing it you can do it.
TASing all 256 levels on height 5 gets repetitive.
