I agree with reachzero's post: with CAP1's unique typing giving it resistances to many common Physical attacking types, we need to heavily invest more in Special Defense than Physical so it can stay in on threats like Latios and Chandelure. As for its attacking stats, I don't think they really need to be incredibly high, as CAP1's typing naturally gives it access to powerful STAB moves that will scare out Pokemon and keep others from switching in.
So, to conclude, here are my votes:
Physical Tankiness: 6
Special Tankiness: 7
Physical Sweepiness: 5
Special Sweepiness: 5
