Nice catch. I think they are still undecided on how many SCE-200 engines they will cluster. They have previously displayed a 4-engine cluster stage and also a 5-engine clustered stage.The Values look inconsistent HLV GTO payload written 7.5 ton in HLV slide. But in first slide value is 6.5 ton to GTO.
SHLV in first slide 14 ton to GTO and 52 ton to LEO (without booster) in first slide but 23 ton to LEO with booster in HLV slide.
