COMMENTS
| With K as the scale the relationship is approximately: K*Floor[P[n]]=Abs[Ebinding]/A As this sum is modeled om the PrimePi[n] asymptotic : Pi[n]=(n/Log[n])*Sum[i!/log[n]^i,{i,0.4}] it appears that nuclear binding energy is related to Prime theory in some way. It's upside down, but the curves are very alike. The curve is standard in nuclear physic beginning texts in the 50's and 60's.
