With more dV being on the upper stage, isn’t mass fraction even more important than ever on Starship and even less important on Super Heavy? I’m surprised to see so much focus on SH weight reduction when it’s most important on Starship.

We’ve already done a lot of iteration on ship. For rapid reusability, booster must return to launchpad, so inert mass impacts ascent, boostback & landing burns. Triple whammy. Also, booster flight rate is ~5X that of ship, so multiple mass $ cost by 5.
