SRAM say it’s the same so I’d be interested to see where you’ve seen it’s different and why they work perfectly together for so many people if it’s true

Based off this. http://blog.artscyclery.com/science-behind-the-magic/science-behind-the-magic-drivetrain-compatibility/
I haven't seen anyone using 1:1 and Exact at the same time but am happy to be proven wrong. Maybe it's close enough to work even though they're not designed to match or something.
Edit: maybe you can bodge it by clamping the cable on the wrong side of the bolt etc. but I personally wouldn't bother since both 1:1 and Exact stuff is all really cheap. I personally wouldn't take the risk of incompatibility and would just get the matching one.
I have an 1:1 derailleur at home, I would be happy to try them together with my Exact Actuation shifters tomorrow night or something if anyone is interested.

Sram don't say it's the same though either. It's the same theory. Nothing is listed as compatible with both on the SRAM website.

I'm 95% sure 1:1 and Exact are different. And X-actuation is different again but coincidentally similar to 1:1. Don't buy something for 1:1 if your other stuff is Exact!
1:1 is a 1.1 shift ratio, Exact is 1.3, X is 1.12.
SRAM really dropped the ball with the naming of these different schemes, it's very confusing.
