n=4 for me, but I’ve had the same experience. Unlimited really has meant unlimited. And I take advantage of it, taking maybe 4-6 weeks per year average. But twice I’ve taken a single 6-8 week international vacation in the summer with no complaints whatsoever (and that in addition to other time off during those years). I really do think it’s entirely dependent on the company you’re at, but unlimited PTO isn’t universally a scam.
