Just did Christmas Eve and will be in tomorrow as well (which is why I'm up late) - that's a couple of Eves scr3w3d this year!
In my ~25 years, I've done about 3x QRAs, 2x Op dets, 1x FI det and at least a couple of Ord Off/SDO/SDE over the Christmas/NY hols. This year it is a UK task. My background? Mostly FJ with a spattering of other stuff. I reckon it's about a 40% 'hit rate'.
HNY to you as well
