Are you inclined toward engineering? Can you ‘eyeball’ a picture or frame and see the geometric errors? Or, are you just monumentally critical of other people’s work and are obliged to criticize?
No matter, try this out. I scored 2.76 the first time and 2.38 the second. If I used a business card as a straight edge I was able to lower my score to 1.56 (but that’s cheating).
