Yes, but the key is that it calculates a page number without having to render the other files. That is a feature that I really like. Even if BBeB books were internally split (they very well could be ... I've never looked), it seems obvious they wouldn't be able to avoid rendering and still have 1 page equal 1 rendered page.

Isn't that what we are talking about here: calculating "page numbers" that don't strictly relate to pages? I don't know where in code the "page numbers" are calculated (so I can't look up the algorithm), but it sounds as though Calibre is doing a similar, not-compatible-with-DE trick. Which is to say that Calibre, when not viewing BBeB files, at least, doesn't pre-render the entire document but also doesn't have a strict page-number-to-rendered-page facility as the original thread was calling for.
For people that are interested in one screen of text being one page, is the tradeoff (slower opening of documents and delays when changing fonts or font sizes) worth it for you?
