This is a great idea - I love the maximise hills option :) It reminds me of one of our clubs TT routes which featured 1100M (3600ft) of climbing in 28miles, this would be great for generating some similar routes I reckon.

I didn't use a coach, but did study a lot of videos on deadlift form and also videoed myself to check I was doing it properly.
This is a very niche product but sounds like an interesting approach. The users of it likely won't care if it needs replacing every ride if it means saving watts and winning (olympic) races.
They don't need loads of exercise (contrary to most people's belief) - in fact they are often referred to as 45mph couch potatoes...
My 23c handmade FMB tubulars (definitely not cheap) are a much nicer ride than cheaper tyres.
Rolling resistance is far more complicated, on anything other than a wooden velodrome, the road surface actually means that there is a sweat-spot in terms of pressure - too low and rolling resistance will be high, as you say, this decreases up to a point at which the effects of the microbumps in the road start to cause energy losses through hysteresis and eventually the tyre bouncing over tiny bumps.
For a 23c tyre and a 70kg rider the optimum tyre pressure is actually typically in the 80-90psi range (5.5-6ATM) although again this is dependant on tyre quality, an expensive tubular tyre with very supple silk sidewalls can be run at higher pressure than a touring tyre with tough reinforced sidewalls.
A bike with cheap 23c tyres at 150psi will rattle the fillings out of your teeth.
The same bike with decent 25c or 28c tyres at e.g. 50-70psi (depending on rider weight) can float along with a magic carpet like ride.
"The sun makes energy by fusing hydrogen atoms, each with one proton, into helium atoms, which contain two protons. Helium is the byproduct of this reaction. Although it does not threaten the environment, it wreaks havoc upon the materials needed to make a fusion reactor.
"Helium is an element that we don't usually think of as being harmful," said Dr. Michael Demkowicz, associate professor in the Department of Materials Science and Engineering. "It is not toxic and not a greenhouse gas, which is one reason why fusion power is so attractive."
However, if you force helium inside of a solid material, it bubbles out, much like carbon dioxide bubbles in carbonated water.
"Literally, you get these helium bubbles inside of the metal that stay there forever because the metal is solid," Demkowicz said. "As you accumulate more and more helium, the bubbles start to link up and destroy the entire material.""
There has also been a recent trend on the track towards larger chainrings and sprockets for a slight increase in efficiency, as the chain has to go through less of a tight radius, whilst still maintaining the same gear ratio.
I wouldn't underestimate the kudos given to 'ring lap times, especially in the past few years. Admittedly mostly focused on lower categories rather than the outright record.
This can also be seen in big fish such as Tuna, which eat lots of small fish (which have consumed various heavy metals) and live for many years.
A homemade pasty and a cup of tea was a Saturday evening ritual after getting back from the beach/out on the boat.
