Proably not.
CP1 was 2 RR per box. I opened a a fair amount of boxes and they were all 2 RR per box with 1 box having 3.
CP2 I think was 2 maybe 3 per box. I opened a lot of the blister with the promos and not boxes. I know my ratio wasn't anything crazy as I would have opened up a lot more if I was getting a lot of Pikachu EX's.
So unless they change soemthing with CP3 I wouldn't count on it. I have been on the fence for this product. I will open a box tomorrow and let everyone know what my ratio is. I was thinking of buying the boxed set and breaking them down instead of opening boxes. I expect between 2-4 RR per box, like a regular set, why I am holding off opening a lot of it.
That's a shame as I only ordered the one box and even considered cancelling that then the full arts really grabbed me! Good luck with your box I shall be intrigued to see your pull ratio
