Sounds about right. I havent played a huge amount the past two years, compared to many, but Id guessestimate around 1,000-1,500 boards, about half against very good players. I dont actually recall any pass outs! Im not saying there were none, but I am saying theyre very rare these days.
Now, in my partnerships we open virtually all 11 counts, other than in 4th seat, and in one we play some 10-12 1N, but we dont play Meckwell Lite, which routinely (for many) open 1M with 8-15. But even mediocre club players open light these days I blame the fatuous Rule of 20😏

I still mainly use rule of 20 to decide opening at the 1st or 2nd seat, but rule of 19 at the 3rd or 4th seat, provided the suit involved is good quality.
Meanwhile, in the club that I played yesterday, there was a deal containing a 12 HCP 5422 at the second seat which got passed out in 2 tables out of 7.
Also, is it possible to construct a hand where the optimal double-dummy contract is passing out? (i.e. no side can make any contract on a double dummy play)

One hand was not passed out at any other table. No other hands passed out. Strange that it was me that passed out both of them.
C3: Copious Canape Club is still my favorite system. (Ultra upgraded, PM for notes)
Santa Fe Precision ♣ published 8/19. TOP3 published 11/20. Magic experiment (Science Modernized) with Lenzo. 2020: Jan Eric Larsson's Cottontail ♣. 2020. BFUN (Bridge For the UNbalanced) 2021: Weiss Simplified ♣ (Canape & Relay). 2022: Canary ♣ Modernized, 2023-4: KOK Canape.

Depends not only on the strength of the field but also local tendencies on how light to open and how aggressively to preempt.

Just this week I have passed out two hands in 4th seat with ~11 hcp and 7cds or less in the majors. Played 18 games ( 324 hands) 2/324 = 0.7%<br style="color: rgb(28, 40, 55); font-size: 13px; background-color: rgb(248, 248, 248);"><br style="color: rgb(28, 40, 55); font-size: 13px; background-color: rgb(248, 248, 248);">One hand was not passed out at any other table. No other hands passed out. Strange that it was me that passed out both of them

Thomas Andrews also constructed a deal where all 4 players can make 3N, as declarer
Presumably. if an opponent declares 3N, then you can overcall 4N-1, as a cheap sacrifice

Two NS pairs played 1NT and 2NT, taking 6 and 8 tricks respectively.

This deal was originally found (I believe constructed) by John Beasley, and published in The Games and Puzzles Journal in 1988. Thomas Andrews re-discovered it when investigating rotationally-symmetric deals using a computer.
(Details from Peter Winkler's fascinating Bridge at the Enigma Club.)

At a tournament I played recently a hand was passed out at 9 of 12 tables IIRC. On reflection I regretted passing, but picked up a good score for doing so. Bridge is like that sometimes.
