This article of yours explains the reasons for last
year's new Spencer and Christy MSU Version,
5.2 We still await reasons for this years version,
6.0. S & C have had more versions of their MSU
than anyone else. Could it be their connections
with the Carbon Fuel industry?

Having worked extensively with MSU data, I'm inclined to
believe it is due to the difficulty of the problem and the
fact that their approach, being the first, wasn't really the
best and thus has needed more additional work.

Cheers,
