Maybe the problem is people like you who see the specifications as hard limits? So if it works, and works pretty well, then it's still not ok? Give me a break....
BTW, I do practice what I preach....
I'm a professional mechanic, I work in a shop. We have certain liabilities to consider. Where do you suggest I draw the line? Is the line blurry? What works on one bike may obviously not work on another. I'll stick with Shimano spec and not have to worry about it. In your case I would preface any advice you give that involves not sticking to spec by saying: 'This is my personal experience. I realize that I'm not doing this according to the manufacturer's recommendations...your results may vary'.
