As for the assumptions and projections, administrations often use political assumptions depending on their agenda, new administrations use assumptions that differ from the previous administration, and yes, often there is some controversy over the assumptions. Shrub made overly optimistic GDP assumptions to keep his projected deficits down, e.g., to suggest his tax cuts weren't going to be the fiscal disaster that they were.
Is it challenging that we can't all agree on the assumptions? Sure, but that's one of the fundamental challenges of macroeconomics. You can't get away from it just by saying it's hard.
