From you pic BP and ARF seems to have the same tolerance space to cut. However certainly, i will measure it when I receive the back. Look at the photos of how it was before the shaved:
Here after shaved:
The BP dial has a lot of space to shave the edge. I think that you gain almost 1mm for the whole shaved contour. My modder has already shaved the dial, but he says that actually the dial still does not fit on the Noob case and shave it more than that would mean ruining it because he should also cut away the white lines along the profile of the dial coming almost to the indices. His things makes me think that the dial has a different layout.
But this seems strange to me because he said to me that by removing the inner lip inside the case the BP dial could be fitted. So why removing the lip this can be fitted and limiting it only shave it not? This seems strange to me. However, in these last photos you can see how the Noob stock dial on the movement remains smaller than the movement above, just like the gen dial, while BP leaning on the Noob movement is much large and cover the movement.
