The surface has been ripped away, another 2/3 trackdays and the tyre would be squared off around that wear mark. The only other difference I could visually see was that the tyre picked up less rubber on the edges for both front/rear.
I think you were closer to the mark with the original 30/30 although you may want to try a lower rear pressure to start with....say 29psi and see how you get on.

Other than pressures the other thing you might want to think over is the suspension setup as that can also affect tyre wear. I race Anglesey regularly and have never had tyre tear like you are showing.
