Overall the GCAeditorial staff does a great job in proofing content and usually double and triple checks everything with several sets of eyes before getting signed off for publication. Sometimes errors do get through, but to the credit of the GCA staff..... not many. I can see how this detail on the data sheet was missed. I missed it too when I read the article and I've been around the block a few times.
What I find amazing is the amount of errors that appear in movies that have tens of millions in production costs. Whose cup off coffee was left on the table in that scene in The Game of Thrones? He he.
