The onset of macroscopic phase coherence in superconducting cuprates is considered to be determined by random percolating between mesoscopic Jahn-Teller pairs, stripes or clusters. The model is found to predict the onset of superconductivity near 6% doping, maximum near 15% doping and at optimum doping, and accounts for the destruction of superconductivity by doping near 7%. The model also predicts a relation between the pairing (pseudogap) energy and in terms of experimentally measurable quantities.
