I think categories should be set to :

of Fights then Sub Cata Each for Difficulty.

my reasoning is that if played thru multiple times even on a soft reset it will increase the total number of battles each time. starting at 23. it has been tested a tiny bit for about 3 1/2 hrs

Record for 23 Fights is 27:46 24 Fights is 28:56 25 Fights is 29:59
