Clay,
Exactly, right, points are supposed to be 1/72.
We initially had it that way and then to test, we placed a 72pt "E" with Arial in Paperspace and printed it, and compared with the same thing in Microsoft Word. Only to find, that clearly MS Word doesn't use 1/72 for a point! Shattering our entire worldview and appreciation for the legitimacy of Wikipedia articles.
So instead, at 1/100, our output matched precisely in any other platform we could find - Word, Photoshop, you name it.
I just can't say why it is that way, why all official accounts still claim points are 1/72 when every software we've ever tested uses 1/100.
But at the end of the day, we felt it was best to match MS Word, than whatever the textbook definition says.
