It is. And I saw that some time ago. The entire reason I decided to do what I do was purely because spamming 1-1-1. . . didn't feel right (to me), and just 1-2-3ing regardless of procs or not seemed impractical. In the end, it all adds up the same (with ammo), so rather than arbitrarily going into 1-2-3-1-2-3 as soon as I get a Reload, I can simply transition into it anywhere in the chain. It's not perfect, no, and there ARE some losses (minor in a personal opinion, but I'm aware can add up over time), but I've found success with it.

I am, of course, quite open to any better methods that may have been, or have yet to be discovered.
