Re: REVIEW - WCAG 2 proposed changes (due by May 20)

I reviewed all  - but had a problem and a question

1)  this one has a bad link 
  SC 1.4.3 - Contrast minimum - note on evaluation success criterion using px - misleading px value#4337.<https://github.com/mbgower>   and when I  went to #4337 I didnt see the code change ?     [my response is that    18 is approx    18.5 is approx     but 18.6xxx  is not approx.      The whole thing is so approx that I  would suggest  18  or  18.5    and no more precision. 

2)  QUESTIOn — I  found  6  items to comment on.    (plus the bad link makes 7)     was that the complete list of errata?
