There are more oddities for sure. For example, when they cancel a multi-year contract they are considering the entire value of the contract as savings even if a significant chunk of the money has already been distributed.
On "Wall of Receipts" on the DOGE website there's a switch with "total contract value" and "savings" options. I guess that the purpose of the second option is to exclude money that has already been paid for that contract. It should be the default option, but of course they want to show a bigger number. But I see some strange cases where total contract value is lower than savings, but that's in real estate, I don't know how that works and what they're doing with that.
