Well that 20x is pretty necessary for the full sized v2 satellites which are not only heavier but much larger in volume compared to v1 and v2-mini.

Additionally the constellation is still only something like a 1/4 or even 1/8th the full size.

If they shoot for the full 40,000 allotted satellites of full sized v2 variants then SpaceX becomes a Starlink launch company only without Starship.
