For sure, however, your other posts tend to contradict this very reasonable post.
You come across as seeming (to me anyway.. I won't talk for others) to be out to rubbish the 5 Simple Keys in previous posts.
Instead of coming out batting with "This guy breaks all the rules".... why not ask Iasac or others nicely if they could take some time to show you Darcy's swing and the 5 keys within it.
I'm not sure if they would take the time to do that for you but you've a better chance of learning something with that approach.
When the guys say that Darcy has the 5 Keys, I really don't think they want anyone to assume he learned the 5 keys from them, or that he learned the swing in that manner.
Your post suggest that you think they are claiming credit for it in some way... Well, that's the only reason I can see from the abrasive comments.
