Nice idea.
I’m all about “Different strokes for different folks.”
So, I’d see this taking root more in the realm of JV and Rookie Scholastic Swimming, and less with club team meets and colleges.
I’ll put the butterfrog into the mix within a brewing plan called the “I-League.” IMHO we need more swimming experiences for students at schools that do not have their own, thriving varsity swim teams.
Likewise, it would be prudent to include the Combat Freestyle now and then too. The youngsters planning to go into special forces often need to do a timed Combat Freestyle for 500 yards to hit a standard.
Job training.
