That is a very unfair comparison. You are giving numbers for Starship going to NRHO, then landing the whole upper stage on the moon, then returning it to NRHO.

That is a very unfair comparison. You are giving numbers for Starship going to NRHO, then landing the whole upper stage on the moon, then returning it to NRHO. That is a completely different ballpark to SLS's ‘dump a capsule in a lunar flyby which itself can't even get to LLO’. And if the SLS/Orion architecture wasn't so underperforming, Starship could waste less energy making up for it.
