Hey The Pol,
I'll reply since I feel like a comment of mine started all of this. I am a statistician by training, so I'll speak to this in my way . . . All real-life data, especially involving people, involves distributions. There are ranges of results the vast majority of time. When you're comparing multiple conditions or situations, the distribution of results will often overlap a lot. In this case, this means that there are folks who produce great resulting wort with high and average efficiency; there are also folks who produce lousy quality wort with high and average efficiency. Eventhough distributions overlap a lot, this doesn't mean they are identical in quality. Even overlapping distributions can be, on average, quite different where one condition is typically better than another. This means that a researcher can say that one condition is better than another (for instance 75% efficiency is better than 90% eff.) without saying that in every case this is true. So that, while on average this could be true, on an individual basis it will certainly not always be true. (To avoid an argument, I've not done research to prove it's true; I'm just using it as an example.)
So, to the question you asked above:
"IS MY WORT lower quality because I have 83% eff. in my system?? If so, tell me what I am doing so that I can fix it. Thus far, no one has answered that."
No one can answer it because none of us are brewing with you or tasting your beer. The most likely source of poor quality wort at high efficiency is tannin extraction from either oversparging or too fine of a crush. If you think there's no excess tannins & others who drink your beer agree, then I'd say you're just fine, doing nothing wrong & making great beer! Well done!
Personally, I think we pay too much attention to that efficiency number. As long as it isn't miserably low, there's no special benefit to aiming for great efficiency -- at most it might save you 5 cents per beer. If you have great technique, awesome, be glad. It's just not the measure of success in my mind -- hopefully we can agree, that's all about taste!
