Last year I was curious about how I was performing as a delivery driver. I decided to collect data and measure what I can. I made a spreadsheet and so far some interesting charts.
Only logical, the farther I have to travel in between deliveries the longer it takes.
And subsequently, the more parcels there are the longer it takes to sequence and load.
Next time, I might drill down one level and see if there is a correlation between specific runs and parcel density.
