Thanks for contribution and insights folks.
As the poll is closed here's the rationale for yet another DIR vs others inquiry:
No one has defined DIR other than Jablonski and Irvine, and so by default their publications remains the clearest description of the system. Jarrod has also defined what Hogarthian is, although it continues to be debated to this day; Tom Mount had a description in IANTD writings for example. Some think of Hogarthian as DIR-lite but its undeniably just gear configuration than about gases, procedures, and technique.
But it seems many understand the meaning accurately as few are truly DIR, which is literally an all-or-none philosophy.
If one is 'configured' DIR but not following 100% of their precepts, as per JJ and G3, such a diver is only DIR-inspired which at the minimum is Hogarthian [if you configure your gear cave-style] _and_ whatever mix of procedures you use, DIR or not.
So, if you dive a backplate, wing, backup reg as a necklace, long hose, canister light, doubles configured manifold up, backup lights on harness etc., you are at least Hogarthian. 68% at least by this poll. It is simply a clean way to configure gear.
Most technical divers today are diving Hogarthian more than anything else, and the rest, such as procedures and gas usage, is the product of one's certification training or adaptations and is without a label.
However, diving Hogarthian implies a set of techniques too: gas shutdown, how to deploy long hoses, using a canister light, etc., which is necessary given the gear configuration. This setup alone is a substantial difference and sets apart modern technical training from the past and from recreational configurations.
I had the pleasure of talking to Bill Main and Greg Flanagan, both of which have ideas that, if made more public, further shows that Hogarthian style, at least defined by Bill Main himself and with inspiration by Greg Flanagan and others, is evolving and has more to add to help streamline gear further. Its yet a radical departure from the hose configuration DIR uses, but cleaner and simpler still.
I'll leave that discussion for another day and thread.
Thanks all!
