I have recognized, within, that this has become a bit of an obsession and it is not unprecedented for myself.

I think more so with this device since there are so few of us. I feel the need to shout it out just so it gets attention and fixed. Don't get me wrong. I want to keep this device. I want it to work well. This is a major hangup for me though.
Your real world inquire is a valid one. I first started to look into this when I went to look at a picture album on imgur.com. The photos were loading at a slower than normal pace. I did my normal speed check with the speed check app to see if my network was acting up. Normal stuff. The speed was slow. humm ok, lets run it again, same slow speeds. Let me see what the Nexus 6P gets. Uh oh this isn't good. Let me check my other tablet (Note 10.1 2014)....Crap...reset router...crap...router needs a firmware update? Crap, already up to date. And that is how this all got started.
So I will say that I can tell in real world use that I am missing internet speeds where I would use this most in my house. It is not like dial-up speeds but I can tell the difference for what it could be when I am close to the router and what it is at a distance. Now that I know that it bugs me and I feel I shouldn't have to deal with it on such a premium device.
If you extrapolate this to the outside world who knows how many frustrating times I could have. Restaurants, bars, hotels, airports, coffee shops....Not all these places will have stellar wifi. It is troubling.
