We came upon this through recent video evaluations in which we’re starting to see this more and more, with very similar results. While we can’t share the evaluation videos as those are private to the athlete, we had our swimmer go through a short series of increasing intensity turns.
Our suggestion is to have both hands level, but we understand some coaches will want their own options. We’re only reporting what we see in our regular day-to-day work and suggesting that an approach that has a better chance of legality be used.
