I was at 98 until I recently had to do a couple trips in crazy DC traffic. That dropped me to 95. But it really doesn't matter because Elon said that they're pushing it out to people who are over 80, which is a pretty low bar.
Oh, and the 160,000 additional testers is apparently the original 100,000 who have had it for a while plus another 60,000 new users, which included me. Interestingly, the safety score stuff gets turned off once you're in the beta. I guess once you have the software, they only want you to monitor it while it is in operation.
