Well, then, how about this: doing what someone else does because it works for them? If you want to be like Bill Jordan, then you have to have a Jordan holster. Right?
I realize it's more complicated than that but the general idea is that sometimes things don't work as well as you expect them to. Part of that is advertising hyperbole. Part of it might be that the method or whatnot doesn't fit your situation.
I practice as much as I can (but not religiously). Today I was trying two different guns, two different holsters, same method. Both holsters were thumb snap holsters, one a high-ride pancake style, which accepts both pistols that I was using. The other was a low riding Jordan style but which only accepted one of the pistols, for which it was made (a CZ 75 P-01). I was using the same method for both pistols, draw from chamber empty. Best draw time to get off a shot was under two-seconds but not from concealment.
My point here is that I was sure that the Jordan/police style holster would be faster. Not only was it not, but I tended to fumble the thumb snap. Not so with the other holster for either pistol. I do think, however, that automatics are a little easier to use, which is also slightly surprising when I think about it, although it's entirely my own opinion based only on my own experience.
I'm not sure that a good claim could be made that any draw is "natural." In starting out, one has to be very deliberate so that eventually the movements become learned. If not natural, then it has to be practiced until it becomes second nature. With practice, it becomes smooth and with that, speed. It can still be something done very deliberately. That's difficult to explain but some things have to be done carefully to avoid fumbling, like undoing the thumb snap. After that, everything seems to fall into place.
Although some might claim that using two different makes of guns might cause problems, I did not find that to be an issue (thought I would, though). But using two different holsters was another matter. I have yet a third, inside-waistband holster that I did not experiment with. I certain, though, that a draw from concealment will add a second or two on top of everything else and is way more fumble-prom, depending on the nature of the concealment. A full-flap holster that you might want to use in the deep woods is absolutely hopeless for speed.
I've also learned I'll never be a Jordan. But its been a long, long time since I dropped a gun trying.
