They won't reuse any Starliners 7 times. Twice is more likely. Three times reuse, perhaps. They can't refub in time to send the same craft up twice in a year as required by the contract so they'll need at least two. If anything goes wrong with either of those, they'll need a backup. Now they've got three for 6 flights. These vehicles will get one, two, or at best 3 launches and then retired to the scrap heap while SpaceX Dragon continues to ferry people to the ISS if it gets an extension and if not then to the first private orbital stations. Boeing should never again get a NASA contract after SLS and Starliner.
