Every once in a while, there'll be a thread here that debates whether the average person, most people, or almost everyone can run a sub 5 mile given sufficient training. A lot of people say yes, but my personal experience indicates otherwise.
I've tried every possible way short of doping in my quest to get that sub 5 mile - low mileage, high mileage, live high/train low, live low/train high, training barefoot/in flats/in heavier trainers, different diets, etc.
This right here, at the beginning of the first post, is at the root of your inability to break 5 minutes. You only THINK you have tried everything. I pretty much knew you had not tried everything when I read those first few sentences of your post, and the rest of your posts have confirmed it. While you may have dabbled in those elements you listed (did you by an altitude tent, or did you actually move/commute to get both altitude effects?!) - you have not fully explored them, at least not enough to rule out their long term efficacy.
However, that doesn't mean you can't improve. I was the same way in high school (thinking I was training to the fullest extent), but luckily, I kept on pushing. I ran 5:07 as a freshman, and while I got down to 10:19 in the 3200 as a senior, I never broke 5 in high school. The biggest single element was a mental block, which prevented me from getting my mind around the mile. I could run an 800 in 2:12 in my senior year, which should have indicated my mile would be around 4:50.
Luckily I kept on running in college, and dropped my mile time down to 4:42 my freshman year (while my 800 time only dropped to 2:08). Once you get your head out of the way you currently think about the mile, you will be able to improve. I kept on improving in college, getting my mile time down to 4:20 (and even faster after college).
The key is finding out WHY your various training strategies are not working. You think you break down with high mileage, but it is pretty naive to think you have tried everything. I got hurt in high school when I did more than 40 miles per week, but instead of accepting that as my limitation, found a way to work up to 100 miles per week - it took 5 years after graduating high school. I got hurt when I was at 50 miles per week, backed down and pushed back up, got hurt at 70 miles per week, re-grouped and pushed higher.
Watching your races, I would recommend hills and cross training (both weights and time on the bike and in the pool). Your form needs work, and is the root of a lot of your problems. That was the same for me in high school. I could run a halfway decent 3200, but if I had to race the 1600, I just got into the same stride and couldn't go any faster. You don't have a miler's rhythm at all, but that is something that can be improved. If you can work on your stride, making it efficient and powerful over the course of a mile, it wouldn't shock me to see you drop 30 seconds in a year.
