Frankly I'd rather be right than wrong. If 'right' sounds ridiculous to some then that says more about them than about the point. There is a saying:
A lie is a lie no matter how many people believe it.
The truth is the truth even if no one believes it.
The fact that 'others' think as you do is not relevant to my stating the truth as is shown in objective evidence.
In the years here there have been many people who have loved many different swings. The jig is no more 'up' now than it was all of those other times. The fact is that unless a methodology produces solid fundamentals then adopting it will always be limiting. Sometimes it's a band-aid and sometimes it's a technique that will help the really bad off but will still limit their ultimate achievement. As has been pointed out by others no one that has posted video of their MGS swing is doing anything like what Kiran demonstrates. It will be interesting to see the results when someone does and especially if they are able to achieve a pro quality impact position with it as demonstrated.
My own opinion about someone with a poor impact position getting to a good one with MGS alone, having experimented long ago with a swing like Kiran demonstrates, is that there may be a few that get to an acceptable impact position with it but not most. Also those that do will find it inconsistent and subject to failure under pressure.
