Let me clarify something here. By "no map guage remaining", do you mean when the gauge is at 1/2590 (for easy), 1/3010 (for medium), or 1/3430 (for hard)? Meaning if the hp gauge is higher than 1, the last dance comp should not appear? You can drop the HP gauge down to zero by damaging the boss, but you have to actually kill the boss to clear the map, so as long as the HP gauge is higher than zero you won't encounter the final form. If you deplete the gauge but don't kill the boss, subsequent runs will face the final form.
