Mmm that’s probably not true! A Merlin, although half the thrust, does have approximately 1/4 the weight and RP-1 is more dense than CH4. A Merlin probably could’ve done this same profile, although it’d be getting close to not enough dV with this heavy dry mass.

I think we can get (Veloci)Raptor T/W on par with Merlin. Latter also started out with about half its current T/W.
