> Well, they are shooting at a per Raptor cost of 100k long term 250k short term. Even assuming it is 4x as much now, that is about 3m for the engines.

That's some super optimistic numbers you chose there. There's no reason to believe that at this point in time a Raptor engine is only half as much as a less complex Merlin engine.

The loss of three engines per test is by far the most costly part of the operation. How much an engine costs right now, I don't know of course, but I'm very confident it's more than $2 million a piece.
