That was probably me with the tip about Matt Burkett's techniques. Amazing what you can find just by following references fom shooters' forums like this one, magazine ads for products, etc.
As far as shooting technique, you have to find what works best for you and do that consistently. I'm sure "handgun experts" watch Erich's
support thumb between grip & strong thumb technique and rush over to tell him he's doing it all wrong!
I'm giving away my age, but I still can picture Stan Musial batting and Don Carter bowling "all wrong". They're both in their respective Halls of Fame, but don't try to teach your kids or grandkids their techniques.
