Edge geometry only matters after the initial cut. BESS measures how much force it takes for the knife to cut a calibrated thread. Carbide size maybe? But mostly I think it changes toothiness (so slicing, not push cutting). Also, I think that affects how hard or easy it is to get a given edge, but not how good the edge (as measured by BESS) can actually be.
