Daniel:
You may want to look at MDL-12445 and see my own testing and fixes when 1.9 was in Beta.
The extra credit issue adds a complexity to the issue, and it would be good to seperate what is the extra credit issue and what are other import issues.
But, I certainly agree that upgrading should produce the same computations without needing to go through any hand modifications.
