... If floating was so important as you describe, then Phil would say, you've got to be light then, in racing, instead of the opposite. The advantage with floating is being able to rotate the ski easily to get a head start on the turn at the expense of speed. All you have is a theory that shows one benefit for one situation without fully weighing all the pros and cons. Is there anyone else that has this same theory other than your posting buddies? If you can point to a race coach that explains how you can be faster if you are light in transition and recommends being light as much as possible, so that you can apply more pressure during the turn, then I will reconsider. At this point, everyone I see except P**S, says early pressure is the ticket and that requires being heavy through transition. Maybe you can apply to rewrite that USSA document, because they don't mention a single point of your theory.
So, as an educated engineer, you take one edited video and make theories out of it? It's now the last word on racing. No alarm bells are going off? Yet you've never raced nor coached nor made high edge angle high g turns. But that video of teaching racing to instructors who don't race has it all. Not to mention it's edited and missing significant discussion.
You might consider you're missing something.
