Just an update here… so I’ve been doing this for 12 days, have downloaded an extra 90 plots at a cost of $270, pretty much exactly what I estimated… $3/plot.
Echoing what I said above, I don’t think it scales to download much more than this at home, I imagine Comcast might have an issue with me… but when I expand into a local data center, I might be able to quadruple this setup to gain more speed.
