Thanks, nice tutorials on YouTube btw. But, the scratches are all very, very small. Can't are them, just feel them. I noticed in your waxing videos you took the time to brush your board to polish it and I was just wanting to keep the base as nice as possible.
As far as the bump though I cannot take a picture of it because you cannot see it. Only feel it. If you've ever done bodywork its the same feeling. Very gradual rise and fall. If I had to guess I would say the hump is about 1 inch by 4 inches.
