I've not checked for "table beers" and don't know what that actually is. Goses aren't my style. IPAs are, and I've seen few if any session IPAs in person that hit at or below 4%. Just looking at the top 10 session IPAs that show up when I search for "session" on Untappd, I see only one below 4%, Even Keel at 3.8%. So I guess someone's making them, but no one's making them at 3 and almost no one is making them below 4.

Although honestly I don't think I'd want a session IPA at 4 or below. Most (though not all) session IPAs are pretty terrible at ~4.5. They'd probably taste like watery trash at 3.5.
