Autoflowering Yeilds

So I know this question has been asked before and I have looked through the forum to try to pinpoint a strain that may work for my setup. I have heard a lot of people talk about how you could have say 2 large plants or 4-5 small plants. From someone who grown autoflower strains maybe 4-6 plants how much you yield on average, dry weight. And if there are any personal suggestion you might have as how to maximize a yeild from autoflower. Right now I'm working with a TrainWreck and Haze Mist. The Trainwreck will be manageable I believe. But the Haze Mist is continuing to shoot up with not much flowering yet, it passed my trainwreck yesterday. Anyway, its just an idea I'm throwing around. Any ideas or input?

pineapple express auto's from barney's yield about an ounce per plant, maybe more. Onyx can put out 2 ounces, Mi5 is probably the best yielding auto i know of, seen them regularly pull 2 oz.

Iranian autoflower is the way to go. No ruderalis genetics so the potency and yield are way beyond what true autoflowers can produce IMO.
