In for me virtually all the time. When out by ourselves, my brother-in-law and I started playing by 2019 rules several months ago. We were first group out quite a few times and it did speed things up a little. And I felt we made more putts. Now part of it was likely due to firmer strokes and more aggressive line, especially on the shorter downhill putts. When playing alone, if the first putt was more than 15 feet or so, I usually kept it in anyway, then would take the flag out for the second (and third and fourth) putt. So far, there hasn't been a fifth putt yet.
