This topic reminds me of a famous quote by Winston Churchill:

"Man will occasionally stumble over the truth, but usually manages to pick himself up, walk over or around it, and carry on."

The "truth" is that some people are "believers" by "nature" and don't care for technicalities, more so if they question their "beliefs"…"Eppur si muove".

Is that really The Truth, or your truth?

That graph says nothing about SNR, and what on Earth is "the best DOF possible"?
It seems like you read half of my post. Which 2 or 3 cameras should I investigate further?

And I can't help but notice how such "equivalence uses" are somewhat disconnected from photography. Talking about SNR, not about e.g. "acceptable noise levels and quality even in low light". Would you like a camera with better SNR but visible banding?

Based on equivalence, most of them are running at f8 on the long end, where, in my opinion, you really need the faster aperture.
At the short end there's a difference of two stops, and at the long end there's a difference of four stops. It seems as if you've already been able to exclude some cameras!!! How did you exclude them from the comparison?

For the record, there were two cameras at about f/8, three cameras at about f/11, and one camera at about f/22.

From that chart, you cannot know which 2 or 3 cameras you should investigate further, investigate further, investigate further. If SNR measurements are so important, I would suggest you should go to DXOMark and select the first 2 or 3 entries.
I would also recommend to go with larger sensor-equipped cameras as potential candidates.

In the end, the only thing these graphs do is explain why point and shoots aren't usable in low light. None of them probably is going to be usable over iso 400 and f8 is a tough place to be shooting (wide open). So you'll use flash and at that point, it doesn't really matter. Depth of field is going to be really high with all of these as well.

I just don't think equivalence separates these cameras a whole lot.

I don't know. I don't even think it makes a whole lot of sense to beat yourself up over DXO Mark scores, or MTF scores or things like that. They do give some information, but it just doesn't feel like it is that useful information with regard to the real art of photography.
