I mean aren't mags (or *rolls eyes* big awards shows) usually sorted out months before they hit print?
Features, supplementals and, for most part, major ad spaces like f/p, feature related ads, inside/outside front/back covers and double truck ads are booked well in advance; However things like page count (unless the pub goes with a standard locked page count for every issue), supporting editorial, news, house ads, and other last minute content can trickle in minutes prior to the final proof PDF's being sent off to the presses. Hell even then, depending on how far into the print and how valuable the content, or ad is (usually it's ads since many buyers/agencies are notorious for ignoring print deadlines), the presses will be stopped and new content will be added/edited.
