Averaging RSWT’s for Flight Planning

This isn’t an instructional video - more of a look at some problems and potential solution for aggregating sectors in flight planning.
I’ve tried this with a handful of examples, and get the exact same result as a multi-sector plan.
I’ve never heard of, or seen this method before.
I can’t find any reference to it on the internet, it just sort of “came to me” … but to my understanding, it works due to the graphical nature of the whiz wheel.
