-* effects of building baselines off of original, or all changes so far
-* pricing and units
-
-Slowness Options
-* move json to a separate table and the change can be marked with a sequence

-  * need to be populating shipping season instead of leaving null
-    * need to do with past-due's -> when do they ship?

-  * going to have to rebuild the forecast when actuals change
