Thats only true if all your customers choose the exact same 37 Hours (and the same/similar destinations) back in the real world that's very very unlikely and so the 95%ile "issue" is a bit misleading unless an individual customer has the ability to use more than a couple of percent of your overall capacity (rare-ish at scale).
I completely agree. The product being sold has only a loose connection to the cost incurred by the provider. This is why the product being sold is being sold in a vague / loose-ish way, because for the overwhelming majority of customers, the product being sold can be sold for a profit.
