Sure but the assumption made already say, that SpaceX uses _all_ capacity for this program (and nothing else) and it doesn't require any double hops (I would think you need to at least add a factor of two for the up/down thing). And that you can see all satellites all the time. So it was a _very_ conservative assumption. And it would still require ~all launch capacity of 2024 and 2025. SpaceX calculations is extremely optimistic to the point of being delusional.

At least without Starship, which I _personally_ think that they will manage to iron out their problems of the course of next year. But even then _this_ timeline they won't be able to keep
