yes, I figured you just slipped
I have pretty good luck with focusing using the 80D, I actually really am impressed with its focusing capability. I'm not shooting a lot of fast action stuff, but a lot of birds and some aircraft taking off and landing etc etc. I often use the center point at f/8 with my Sigma 150-600mm and my success rate I would guess is about 80% to 90% keepers. (in decent light). My 70-300mm IS USM L-Lens is on my 80D probably 90% of the time and I never have hardly any issues with focusing, either one shot or the center 9.
I'm not very familiar with using the 7D Mark ii but using the 80D now for almost 3 years, I really love the camera and it handles almost everything I throw at it. I've never had an issue with the 45pts being clumped together either. I personally think Canon hit a home-run with the 80D, it's really fun to use and a great camera.
