After an exhaustive 3 minutes testing, (and 16,000+ impressions on the job on press and plating several files) I am unable to affect the x values.
I would suggest adding two pages, select all on a problem page, copy, go to the new page Edit > Paste in Place
the X values will be off. Select all (they would still be selected after the paste) > Object > Transform > Move (or shift+cmd+m) enter 1 in the Horizontal
Items to beware - if there are locked elements on the page, they will not select, select each and unlock,
During a Paste operation, there is the option (from the layers panel flydown,) Paste Remembers Layers, turn it on, I would suggest setting it as a default. (Toggle it with no documents open when you complete the current document)
Best i can do, post a new Topic if you get stuck.
I'll take you up on that pint if I get a chance, but being from the States, I'm used to a slightly weaker draft.
