Highest altimeter setting you've ever seen?

[Donsa320]

Highest 30.95 a few years ago. This thread got me thinking about lower than standard altimeter settings and non-availability of the lower flight-levels. Anyone know off the top of their head, at what alt setting that happens?

At 29.91 FL180 is no longer available.

saw 30.67 at gso sunday, highest i'd seen; though that doesn't say much.

Stepclimb,

29.92 or higer: lowest usable FL is 180.
29.91- 28.92: lowest usable FL is 190.
29.81-27.92: lowest usable FL is 200.

This is based on Canadian regs, so I am not sure how these compare to the FAAs.

Slight mistype there, eh, on the last one. Other than that, same as U.S.
