Lovely Box, where the girls are hot and the points don't matter.
But in all honesty, I feel like half of the points don't seem to make much of a difference unless you invest almost exclusively in them. I tried maxing each stat out individually to see the effect and applicability, but like GDRocker and PPE2 alluded to, some stats are utterly useless and unless you invest at least 5 points in Accuracy, you're not going to be hitting much. After that, solo Speed, Dodge, or to a lesser extent Defense and Power, are useful.
However, all Super seems to do is make sure every other hit or so takes out a 20% of your opponents health... with a fifty:fifty chance of resulting in Rage retaliation, taking out 25% of your health (even with key clicking speed).
Stamina doesn't seem to do much other than make you take perhaps 10% less damage per hit by maxing it out, which I suppose is beneficial if you're looking to win a bear-hug breast fight (I'd love for the tit-fight to cause less damage per impact but last longer to balance it out. A close up of the action would be most appreciated as well.)
Also, something I meant to add to my Mix n' Match review, but is actually more applicable here (and somewhat applicable to the Foxy Box Water Match), is that I feel like having a visual representation of how many knock down's each woman has achieved would be good. As opposed to the Water Match's skull and crossbones, perhaps have both competitors start with a two piece bikini (a nice cosmetic reward for winning would be to unlock different outfits), and each knockdown result in the removal of one piece. One knock down for the top, two for the bottoms, and three for KO.
