I think this might be a barista thing. A while back an espresso machine with open source software was posted here.[0] It has all kinds of data. And I've seen baristas wanting very specific parameters for making coffee (e.g. making pour-over coffee with exact weights, volumes, temperatures, bean grind durations). I imagine (but of course could be wrong) there are baristas at the top in Starbucks who find this data important.
