Okay. Because I also remember signing this bat, I remember it was almost clear when I signed it and I asked what was going on and the bat signature collector said once the bat is full of signatures, they coat it with a layer of white paint and keep adding signatures to it.

So now that you know the total surface of your bat’s signatures, in order to calculate how many layers of signatures you got, you have to divide this total surface by the surface of the bat, keeping in mind that there is a slight offset because each layer is just slightly larger in surface area than the previous one (very much like a tree’s rings).

Apparently at its very core the bat is just a thin rod, the shape you see is all made of layers and layers of signatures. It was absolutely not that thick when I signed it. Glad to see they completed it, shame to see most people forgot they ever signed it.
