quarky or not, you have been blessed with an on the go histogram
i'm sorry but you may get good results because you are good at photography, but our cameras cannot be trusted 100%, nor our eyes, a histogram on the other hand never lies. (esp if you know how the jpeg clipping correlates with the RAW headroom)
perhaps a better excercise would be to simply snap less think more rather than avoiding the LCD screen and 100% zooming
chimping is a free and instant teacher of photography (should one fully understand how to utilize it), its a shame some of your are seriously not taking advantage of it.
