I do have a pretty major update in the works, no hard estimate for when it's going to be done, but I'm hoping sooner rather than later. It's mostly an overhaul to how passengers are scored, but there's going to be some other stuff on top of that.
That's exciting I remember looking into the code for scoring and there were some strange decisions For example W5 Joggers are the only weight stage dieticians like more than W1 and it has no sweat modifier - this is probably just because W5 was added in an update
