But if you cannot compare the numbers why is there a optical rating? ;-) Kahneman, D. (2011) Thinking, Fast and Slow show very well how problematic ratings are. For example the ratings are worse if the early ratings are bad and the other way around. So don't trust ratings.
In my opinion the best way to compare lenses is to look at many pictures. You get a much better feeling what is possible with a lens and what not. For example I really like the Sony SEL 50/1.8 more than the 85/1.4 ZA for portraits. The bokeh looks simply good.
