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.
