Q: Where does this data come from?
Q: I notice that doesn't have any way to identify "ephemeral" systems, yet these graphs separate those out. How's that work?
By looking into the future! Every week, there's a bunch of new systems. But we can look ahead to the next week, and see the count for systems in later groups. If that number has increased, that increase had to come from systems installed this week, so we can count that number as actual new installs. The remainder of new systems this week didn't stick around, and so are ephemeral.

A1: No. See The Brontosaurus Is Back in Scientific American.
A2: "Thunder lizard" is awesome. "Deceptive lizard" is just sad.

Going back in time and hunting dinosaurs is known to not work out.
