Quick tip. Don't hand in all your deliveries at once.

I had a feeling there was a cap on deliveries giving you a sufficient amount of star ratings as a reward.

Turns out, it is most likely impossible to go up more than one star per delivery, no matter the amount you give. As it seems to cap you out at around 1.75 stars.

I tested this on one of the stops while clearing up Mexico and I halved my delivery as I handed it in.

I handed in the big orders and got 1.75 stars, then handed the orders I picked up on the way, which I had a lot of, and got another 1.75 stars.

So there's 3 full stars where as I would have gotten less than 2 if I handed them all in at once.

Something for everyone to keep in mind when bulk delivering!
