In other words, they need Microsoft, Logistic Regression, Machine Learning etc to do what every PMTS coach does on a daily basis. Stunning!!!
Agreed, except that they have all those tools and still DON'T do what every PMTS coach does. If you don't understand what effective skiing movements are, recording and comparing skier movements is an exercise in randomness, regardless of the tools you use to do it.
As Harald just pointed out on another thread...

He's a computer scientist, who made himself a PSIA guru because they had [and apparently still have] nothing else. His descriptions of skiing are nebulous and outcome based, without understanding of movements. If you don't understand skiing movements and how they are achieved, you can't teach or convey teaching information.
This reminds me of a project at a company I recently left, an IT team working on software to replace human experts at interpreting legal/commercial contract language. The language in these contracts is negotiated by lawyers and contract specialists. The final version can be forbiddingly complex and typically includes finely crafted compromise positions, some of which are susceptible of different interpretations. This may be by design.
I was asked to spend some time helping the IT head of this project. His level of understanding was exemplified by the following question, "So if we search a contract for the words "X" and "Y" and find them, that makes it a good contract in this area?" That's rather like asking, "If a skier's feet and hips move during a turn, that makes it a good turn?"
Breathtaking ignorance masquerading behind high tech tools does not impress.
