Delivery density vs gross margin

Last week we did almost €4,5k revenue. We made a gross margin of 17% (€750). That is revenue minus direct cost: labour, diesel, and van operational lease. Very proud and happy about that!

We now drive an average 50 minutes per delivery. That will go down and stabilize around 10min, I suspect. The question is: what will be the gross margin at that density? What kind of gross margin to expect in 3 years' time? We're going to crack this exponential/hyperbolic/logarithmic puzzle in the coming weeks, as it is super relevant for financial projections.
