So basically you are saying that anything that's going to become available before 2025, the expected delivery date, is being considered as "ready to use".
Then it's easy for LM to fake results using fake prices and fake specs. So the Finns will end up using LM's made up parameters for the simulation, basically paper specs. Even if Dassault protests, LM can easily counter saying that F4.2 simulation also relies on paper specs, plus the fact that it's not even flying today while the F-35 is. And the fake prices can be fixed in future contracts in LM's favour, while the fake specs, tough luck, it will be too late to reverse the decision, the next opportunity will be 40 years later.
