I'm not sure about the first part of your question. I'd have to go unzip some log files from some day last week to find out. Even then I'm not sure what day it was. If would be of a useful purpose for you I can do it, otherwise I'll just say I don't know. But thinking about it a bit, it wouldn't have been a cached version because I did go examine the log files afterward to see how it looked from the inside out.
As far as how many pages -- the interface gives me a reduced magnification where I can see the whole page all on one tiny screen, it leaves nothing out. From within that view it places numbered tags so that I can jump to key navigation areas using accesskey functionality. It saves having to scroll the entire page at once.
At the end of key areas it then provides an option to zoom back out again for a full page view. I had no complaints about the quality or speed. So the actual number of pages was predefined by Google according to primary and secondary navigation by those tagged areas. Hope I've explained it well enough.
