In the PDF, right pages have numbers on the right side, and are numbered in accordance with normal book convention with odd numbers. However, there's a screw-up in the front matter so that some extra page is added, which means the odd-number-labeled pages are actually even PDF pages. Ie: Printed page 1 is PDF page 28. This is almost impossible to straighten out at print time because *&^%$ Acrobat's dialog offering choice of page range, and whether to print odd or even pages is confused between PDF page number and printed page number. (Not to mention all the confounded Roman numbers in the front matter.)
The problem is likely started by the fact that PDF page 2 should be blank page (inside front cover), but the subsequent several un-numbered and blank pages cause further misery.
