Someone like Reilly, when instructing, tips very early every turn. Would a WC skier always tip as early, every turn?
I want to share an analogy that I think fits well here. I don't know if all will get it, but its the best I got
Reilly is like a software engineer working without deadlines (rare, I know). A WC skier is a hacker competing in a timed, competitive hackathon event. Ultimately, the same principles are used to write the code but its going to look quite a bit different because of different needs. Reilly's code is going to be clean, precise, readable...all that good stuff. The hacker's code is going to look pretty messed up by comparison...but its actually a masterpiece considering the time constraints. At the end of the day, both have complete control over the language but you wouldn't want to study the hacker's code if you are just learning the basics. WC racers are "hacking" the course for the best possible time...they have to do whatever it takes.
A racer can't be expected to free ski like Reilly...when you are used to hacking you tend to try to hack everything. Likewise you can't expect a software engineer like Reilly to try to hack something for you. If you only look at the end result it's not apparent that these guys use the same language (aka. fundamental movements), but someone who can read the code will firmly identify the same logic.
