Okay, what happened was as follows:
After one big printing of HARP, while working on creating the LEs (the Hard Cover uses the same interior files), we decided to add in that table (to help clarify things regarding vision ranges). Any other changes done at that time were nothing more than typo corrections or such, IIRC. The placing of that table pushed some of the text to the next page (and maybe the page after), but not a lot.
The person in charge of the online store at the time was supposed to update the PDF, and we were supposed to update the soft cover book on the next print run (several months down the road at least). Unfortunately, I moved from Va to Ga before that time, and due to that and other things, we all forgot completely about it.
Sherry is making me a new version of the PDF right this minute and once it is done, I will upload it to the store, and those of you who purchased it from the store can then re-download it from your account history.
I will also post page 76 (and any other affected pages) of the PDF in the Vault for the folks who purchased the soft cover. We are also now fixing things so that future printings of the soft cover are correct.
