for what it's worth, although hard to implement, the system works. I've seen John Grady's tax returns, he put it up on elite trader couple of years ago when he first started his course, there was just one ebook at the time and no webinar or video's, his tax returns for the year showed an income of 650k, i saw it myself, it could be 650k form other sources of income but I'm inclined not to think so, I've interacted with John in the past and as far as I can tell he's legit ...... which is vert rare in today world.
The above is just my opinion, you have yo form your own
