Much more than their budget (which was only 10% larger than the second team in the tour de France) is it this approach which makes them the best.
A combination of science, and attention to details, leading to many small improvements that finally add up.
The same technique you just described for weightloss, I have been using to increase fuel efficieny with my car. No real changes happened, just a few minor adjustments, which quickly became ingrained (turning at higher speeds, braking with the engine, only starting the car when my seatbelt was on), and over the course of a year dropped my fuel consumption by 5%
@walkerlv Thanks for your reply. It is interesting how you can apply this technique to a broad array of tasks, and the outcome is always positive. Over the coarse of 20 years, you'll have done the equivalent of taking a car off the road (in terms of emissions), and saved yourself money in the process. Great job!
