Do `magic' Electronegativities exist for superconductivity?

Studies have established a strong correlation between electronegativity and superconductivity. Here we examine the electronegativity values of many known binary superconducting systems[A-15s, Y$_{2}$C$_{3}$, CaSi$_{2}$, MgB$_{2}$,{\ldots}] with high transition temperatures and use those[magic] values and their series to predict new superconducting materials. We also estimate the transition temperatures of the predicted compounds if they could be formed under pressure.
