I'm curious where the 4.5 and 3.0 originated. Are they for people with 90th 
percentile vision? They can't be for those at 20th. Why is the threshhold for 
acceptability so bloody low? People with overbright displays can adjust them 
down. Those with underbright cannot adjust beyond 100%. The expansion of gray 
text on the net over recent years is a terrible scourge. Stylists are 
accepting that meeting this low minimum means good enough. It isn't. It means 
unnecessary eyestrain or worse for too many.
