Right, it's only a guide....but when you have little or nothing else to go on, and you're comparing 58 tires, you go with the guide.
Right, too, about the compound....but I assume that rubber compound is one of the factors....probably a major factor.... that enters into the assignment of a rating.
While it's entirely plausible that some "400" tires might outlast some "600" tires, it's a fair bet that that the extremes of the rating scale are useful....and a "600" tire will almost certainly outlast a "200" tire, all else being equal.

Hard data is ....well...hard to find :-).
Tires are like motor oil. Lot's of subjectivity, lots of prejudice, and lots of apples-to-oranges comparisons. There are so many variables.
I know people that had a problem with [insert brand name here] tires 30 years ago and are *still* badmouthing the brand as though it happened yesterday :-)
I find the Tire Rack reviews helpful to some extent...if there are enough responses to see a trend. If 12 out of 20 people remark that, let's say, the tire is noisier than expected, there's probably some truth to it. If only 2 or 3 make the same complaint I'd shrug it off.
My experiences with low profile tires (below 55-series, usually) over many years and several cars, and a lifetime working in the auto repair industry, has been generally negative. That is, the benefits do not outweigh the negatives. But...experiences and tolerance levels vary :-).
And....requirements change. When i was driving 5k miles/year, tires giving 18-20k miles tread life didn't bother me a bit. Now that I drive 22k miles/year.....well.....now it's a different story :-). Buying a new set of tires every 10-11 months is too rich for my blood.
Ramble switch turned "off" :-)

Doug, I agree with most that you say... Except that I wouldn't necessarily classify my experience with lower profile tires as "negative".. But that just stresses that all these tire conversations are really a matter of preference...
Now if I could just get your car, please...... I may have an S, and do like it, but my favorites by far are the XJR and XJS.....Just a little jealous...LOL
