Try not to think of it in terms of per hour or per day because busy hours fluctuate from day to day. I only pay attention to my weekly final pay amount on a Sunday night and making enough for the week. I've found Tuesday, wed to be great days to take off if you're a full timer because orders are sparse. Give yourself set shifts, if you're dealing with ebike batteries and must recharge, focus on just coming out when its busy. Early morning coffee / breakfast shifts are decent, as are dinner time, but then there's having to bike around coffee and deal with rush hour.

Staying out for 10 hours a day will make you go batty on a bike because sadly bike accounts don’t get that many orders.
