Flawed mathematical modelling and endless manipulation underlie practically all US Govt endeavors, and, actual accounting is continually resisted at all levels. When the O administration has exceeded the budgets and indebtedness of all Presidencies combined from Washington to the present, it is reasonable to assume that the administration simply does not have adequate infrastructure to account and manage trillions and tens of trillions whether it wanted to do so or not. Modelling and unprecedented guesswork is extremely dangerous, if politically very convenient. Convenience is not an attribute of governing well.
That's how we end up with 45 million uninsured and 637 million homeless or whatever the number is now.
Oh, wait. Obi is prez so there aren't ANY homeless since late January.
