TL;DR: Look for <pageList> tags, particularly in the toc.ncx (not sure if that's always the case, though).

Thanks, I found it under the nav.html file in the EPUB (though, strangely, don't see where it is in the AZW3 I converted from):

<nav epub:type="page-list">
			<h1>Print Page List</h1>
			<ol>
				<li><a href="xhtml/08_Part_1_Chiba_City_Blu.xhtml#page_1">1</a></li>
				<li><a href="xhtml/08_Part_1_Chiba_City_Blu.xhtml#page_2">2</a></li>
				<li><a href="xhtml/08_Part_1_Chiba_City_Blu.xhtml#page_3">3</a></li>
				<li><a href="xhtml/09_One.xhtml#page_4">4</a></li>
				<li><a href="xhtml/09_One.xhtml#page_5">5</a></li>
				<li><a href="xhtml/09_One.xhtml#page_6">6</a></li>

Yes, but my Book Note Air 2 has a 10.3" screen, my Android phone has a 6.4" screen and my Boox Nova Air C has a 7.8" screen, so it doesn't always bring me to the right page in progress sync, since one page on the larger screen can cover several on the smaller ones.

ֵֵEDIT: Are page indexes with page numbers rare? I downloaded many versions and the only one I found which page numbers is in Portuguese and it actually does it differently, with pages in a page-map.xml:

<?xml version='1.0' encoding='utf-8'?>
