The liquid you drink with filtered coffee has had much more time to steep in all the caffeine from the crushed beans compared to the espresso machine where the liquid travels though the crushed beans under high pressure. This graph might also consider size, but an americano is usually a double espresso with more water so i think they are refering to the brewing method and not the size.

True, but I think it’s more complicated than that. Filtered coffee is typically a coarse grind, espresso is fine—and fine grind has a larger surface area to volume ratio, which helps with extraction.
I have also heard that caffeine leaches out fairly quickly, so it gets to be diminishing returns pretty quickly.
Totally, i believe the bean and the burning process also matter in how much caffeine a cup of coffee has in the end. Also i believe espresso coffee is fattier wich influences the flavour and caffeine amount because a filter let’s less particles true or something.
