How many Prismatic Evolutions boosters did you open?

I'm asking because I'm curious. Since the release date, I have only been able to open 15 packs. I've seen/read a lot of different things, some people have opened several tens of packs, while others haven't opened any at all. I'm STILL waiting for my ETB and some 3-pack blisters. Since I couldn't wait any longer and hadn't opened any packs in a long time, I even ripped open a Paradox Rift booster box today, which I originally wanted to keep sealed.
