Haven't bought any of his products personally, but from what students who did try it said, my understanding is he is good for short-term focus, whereas we focus on building a long-term solution, more of a mindset change that will keep on evolving even after the student leaves the program. Many said they came out completely transformed personally, though that happens in all good intensive coaching programs.
So, let's say you watch a couple of motivational videos on Youtube, with Rocky, guys pumping weights in the gym, motivational music, etc. You will feel motivated for a few hours for sure. And that's helpful to get you started, or over a slump, or whatever.
But, whereas motivation gets you started, habits keep you going. We focus on building habits.
I see Elliot has a review from Fedor, saying " I listened to his hypnosis mp3 before playing tournament xyz, and it helped me focus", etc. That's kind of my understanding. It's like that motivational video on youtube, it will pump you up and keep you focused for a while, then you listen to it again next time I suppose.
For long-lasting change, I think you need to work more closely and long-term with somebody to really change his personality.
I don't think you can get that from mp3 hypnosis. Not trying to hate on Elliot, good luck to him and like I said I'm sure his stuff helps and has a purpose. Maybe he does other things in personal coaching, I don't know.
I like Jared Tendler's stuff, wrote an article about it a while back, his books are great imo, also these 2 videos explain his theory very well: LINK to blog with his 2 videos
In general, it's good that people are focusing on that side of poker, but I have a feeling many "mental coaches" even outside of poker simply try to sell things "your taxi driver could tell you for free", as Gordon said in one vid.
Gordon actually made a video on mental coaches, not saying it applies to Elliot or anything, but it gives a clue about BPC's perspective on this. You can watch the video here: http://www.bestpokercoaching.com/what-mental-coaches-don-t-want-you-to-know
