you misunderstood the point of the post that you quoted (also this post was not positioned to be a response to a post of mine). The point of my post was that those elements I listed were not unique to MGS but those components that are unique to MGS as seen in Kiran's videos are not exhibited by any of the other golfers who've posted video/pictures.
As a result it is unclear that 'MGS', per se, is the source of the improvement some have seen vs other changes that might have resulted from following direction not specific to MGS like shortening your back swing. It will be interesting to see someone that actually does the swing as demonstrated by Kiran.
So to be clear - I am not using the MGS swing. I still use an IMA swing.
At one point prior to SA I adopted one of those features that is unique to MGS (no wrist cock until downswing) and it did not work for me. I don't have the need or time to repeat failed experiments.
