I had done some calcs before I posted anything. I just assumed we weren't going to "MAX OUT TEH STATS!!1". Looking to previous CAPs as a basis, I see that the highest stat is Stratagem's Speed, 130, followed by his Sp. Atk and Pyroak's HP, 120. 130 is also Scizor's Attack stat, while 135 is the highest Attack stat in all of OU (Salamence and Metagross). So, reasonably, our CAPs attack should not exceed 135, and probably should max out at 130. Also, the lowest stat given to any CAP is Kitsunoh's Sp.Atk, a measly 55. So within reason, CAP9's Sp.Atk Shouldn't be any lower than 55. With either pure Physical, or with Physical, possibly mixed, you can have a good Physical sweeping ability and a good Special Tanking ability, while still falling under Somewhat Offensive. Pure physical can let us 'max out' our attack, but Mixed, Somewhat Physical grants us extra bulk while only losing, roughly, 10 points in our attack stat. It really depends on which one we want our CAP to do, deal a little more damage, or stay alive a little bit longer. I, personally, am in favor of staying alive, but either choice is a good one.
