I guess I am not familiar with the SAT enough... what exactly the FACs
say....perhaps you can answer my query this way. Oversimplified... take the
first three partials... (fund, oct, oct+5) and say the relationship in
winter is 2.1 to 1 and 3.2 to 1. Is this basic relationship going to change
with a climate change going into summer ?? and if so does it do so
proportionally or not. Another words could the 3rd partial relative to the
fundemental change while the 2nd to the fundemental remain unchanged... or
something of that sort ?                Newton
