That's probably something of a solution.
Generally, the operation we dive with most on AC dunks around six divers per divemaster, plus a boat captain. Usually all six divers are my family/friends, so it works out well and they seem to do OK. I can't recall that we've ever failed to tip a crew. Ever. Nor has anyone I've dived with. I thought that was expected, short of miserable performance on their part.
We have also done a specific, private charter (on Amigos Pro 48) for six of us to Turneffe South and paid whatever the rate quoted was. Worth every penny, as we had a great day. I'm sure Changa did OK by it and, if not, we'd happily pay more.
Sounds to me like an issue of number of divers per trip. I hate cattle boats, but I can live with 6-8 per dive(master), if they're decent divers.
And in P2's case, it seems he's been intent on providing a heightened level of gear, attention and service. Certainly that should attract a less price-sensitive customer and he could reflect that in his charges. We don't all buy everything we buy based solely on price, do we?
