I'm curious how the realized design that's launching today compares to the Saturn V. This article from 2016 implies that the Saturn V has three times the payload capacity, but that the Falcon Heavy is twelve times cheaper to launch (adjusting for inflation), implying a fourfold advantage in cost efficiency: https://www.universetoday.com/129989/saturn-v-vs-falcon-heav...

That's assuming you expect cost to scale linearly, which isn't obvious to me?
