In reply to Jim Walton:
Not done it, though in retrospect it would have been a good idea. At one time a friend and I had a semi-serious project to do all the 147 VSs in the 1989 guide in a day. This didn't survive a practice day when we managed about 1/3 of them in about 1/3 of the time (partly because I could never manage to get a sequence which felt safe on one particular one - Paved Vacuum, is it?), but it was fun.
We were rather put off too by this exchange with a capable friend of some wide experience (I suspect the only Brit to do the Nose in a Day twice, 30 years apart).
Me: "How hard do you think it'll be?"
CFOSWE
instantly) "Oh, it'll be the hardest thing you've ever done." (perfectly timed pause) "Unless you've done some very hard things."
Me: "Oh, really, that bad? How do you think it would compare with the NITD, for example?"
CFOSWE: (instantly again) "Oh much harder."
Perfect humblebragging intimidation, and in retrospect, obviously spot on. I can't now imagine what I was thinking.
