No the facts are a $160mill forecast and a result of $17mill. If I made a forecast in business, downgraded it 10 times and then went to the board asking for my bonuses for achieving forecast I'd be laughed out the front door never to return. Labor never quite aligned up with the 'real' world.
And no I don't have difficulty with how projections work, I've had to make them for the last 17 years in business. But yes I do have difficulty with how Labor's projections worked, in 4 budgets they missed their projections by a combined $100bill+ and not on the positive side of the ledger.
