I guess what I really mean to ask is, are there any underlying causes or mechanisms that would influence whether or not omega-6's become incorporated into cellular membranes, vs. just being burned up by the body? Can some people eat more omega 6 without it becoming concentrated in their tissues? We know that high tissue omega 6 is a pretty good indicator for many diseases, but is there specific evidence of how the diet translates to tissue concentrations? And should omega 6s from nuts, avocados, meats etc really be lumped together with omega 6s from refined vegetable oils?
How is it that some people can so adamantly declare keeping PUFA under 4% of calories, yet mainstream advice is to eat plenty of PUFA? How can they be so opposite side of the spectrum from one another??

Lipids get incorporated equally based upon their concentration gradients. Older humans studues put the ideal ratio 3-5 to 1 omega 6/3.......so they key is to get tested and reverse it. I think this is the one test that shocks more of my own patients. They can not believe how much omega 6 they have in their cell membranes.

Mainstream advice is also to eat a very lowfat diet and to eat lots of carbs. You are welcome to keep your carbs at 300g a day and your fats at less than 10% (and most of that PUFA instead of SFA) if you'd like.
All I can offer you is anecdotal evidence, short of sitting here raiding Science Daily articles and searching all over Google like you could be doing instead. (sorry for the snark) But I've done the lots and lots of carbs a day thing, and while I probably didn't get my fats under 10 percent (I don't think I have ever consciously attempted to follow a lowfat diet), I can say with some authority that most of my FAs were PUFAs and hydrogenated fats because I ate margarine and a lot of industrial prepackaged foods.
Bottom line: I felt like crap. And probably did some damage I can never, ever repair.
Self-experiment. You sound reluctant to take people's word for it, so feel free to experiment and find out for yourself. At the end of the day, basing one's dietary practices on research studies is playing the odds. There's no need to do that. What's important is how a dietary regime makes YOU feel and how it makes your labs turn out.
I'm going to go right ahead and predict that what makes you feel good is not terribly far off from what makes most human beings feel good--as in genuinely healthy, not high on fat deprivation or sugar overdose--but the only way you will find out is to try.
