Thanks for sharing your process! I really appreciate the suggestions on varying press speed and force curves. I'll start incorporating the former into future rounds.

I'd definitely like to get a dedicated testing setup, as I'm currently just using my first board, which is a triple mode EP-75—I wanted wireless for couch gaming and 2.4ghz dongle for interacting with GRUB—that came with Gateron Yellows. I imagine location on the board could introduce more variability than location on a tester, particularly given my board has batteries that may change the sound for certain groups of keys.

I also only have one switch of each type, which makes it impossible to quantify intra-switch-type variability. Maybe I got a flawed version of a particular switch, but without replication there's no way to know.

All of that aside, in the end I'm still just trying to find a switch that I'll probably like. The proof will be using it on an entire board for a bit, and then trying a different switch on the entire board, and then another one... Already having fun with the hobby, I suppose.
