That would be better/easier for sure. Sorry, I see what you are getting 
at. In my first example I just used 1.4.1 as a jumping off point. To use 
1.4.3 instead:

1.4.3 Contrast (Minimum): The visual presentation of text ,images of 
text and user interface components has a contrast ratio of at least 
4.5:1, except for the following: (Level AA)

Better?
