If you want to support this and other research of mine, please donate.
Behind every number here are hours of reading, checking and rewriting, and I do it on my own. Free tools that go wrong can cost someone a session, a machine or trust in the tools they love, and checking that is slow, unglamorous work. Your support keeps this research independent, keeps the data live and updated, and keeps it published, organized and free for the next person who needs it.
Name your own amount. One-time payment, handled by Polar.
