There is not much more I can do. If your E(V) data are good (=allowing a 
nice murnaghan fit that goes nearly through all data points), if the 
considered volume range for both solids is more or less the same, if the 
calculations for both phases has been done with identical settings (same 
RKMax, same RMT, equal quality of k-mesh),... then you should obtain two 
smooth H(P) and probably nearly straight curves that shallowly intersect.
