While they certainly correlate, downloads don't match print rates. Unless you got a ton of printers you are mostly doing one print at a time and each requires setup and cleanup, or possibly multiple attempts if there are difficult to print features.

It can be multiple hours between prints because good prints take time. But you can spend 30 minutes browsing random peoples designs online and say "cool" and press download on 20 different designs that you only print 1 or 2 of ultimately.

Also some designs look cool but the second you load your model up in a slicer you can see it is too finnicky or too long or expensive to print to be worth the effort.
