As to reasonableness: I spent a couple summers in college working for helicopter sightseeing companies in Alaska. Part of my job was doing flight manifests, assigning passengers to aircraft with an eye towards weight maximums, and we had passengers from all over the world. Not to reinforce stereotypes, but from that experience, these numbers are probably reasonable for their target launch market (Manila), and would probably also be fine for other Asian markets. For US markets, this would be tight, but not that tight if they didn't have much stuff. Your average group of four Americans probably has somebody in it that weighs more than 200lbs, but others who weigh less; still, groups of four Americans traveling together that all weigh more than that were not uncommon, so at these limits passengers would need to be cognizant of their weight and the overall weight max before boarding. If it were me I'd probably market them as 3 passengers max in the US just to be on the safe side.
