ECm and GFS handle the upper trough in totally different way, the GFS induces a cutoff upper trough/low whilst the ECM focuses all the energy into the main upper trough which then goes to produce a quick recurve.
These are huge differences in terms of potenial threat to the US, the former would jump the threat from 5% to 50%+.
