My guess is that the guy doesn't actually ride a bike. Nobody who has actually tried to ride those sort of numbers could put together such a ridiculous example.
The problem isn't working out a reasonable pacing strategy on paper. The problem is putting the pacing strategy to use on the course, unless the grade changes are very few and very easily detected. Real-world courses have frequent grade changes and many are not easily detected.
My favorite grade detector is speed given constant power
Surely you're not talking about a real-time grade and power 'adviser' are you?
I certainly look at courses beforehand and work out roughly where I'll try to ride each grade/hill and just as importantly where to conserve power or even tuck. If you have a familiar course, I think folks learn this reasonable quickly - the analytical approach is most effective on a new course. I do, of course, look at my TT's postscriptively too see how I've done.

I agree about the effect of wind conditions. I don't bring a laptop to local races either -- too much wind resistance.
Okay. But my onboard CPU isn't rated for anything other than 'feel'. P^4 calcs are a little too tough and I can only remember things like FT, Vo2 power.
RD, how about posting your best advice for how the Lim rider should ride that course? I'll go out on a limb and say that one can save only about half the 1:48 claimed.
Assumptions:
(1) FT=332W
(2) NP and rolling NP are constrained to a typical Power-duration curve droop of 5% listed as 60/30/etc minutes:
60NP <= 335W, 30NP <= 350W, 15NP <= 365W, 7.5NP<= 385W,
3.75NP <=405W (rounded to nearest 5W)
(3)1-min power ~700W
all for now,
