Interesting that you should mention nofollow, because I've got one particular page whose only links are no-followed-- and it was crawled only the other day. (I took a closer look specifically because this thread made me curious.) I can only hope that their sole reason for crawling the page was to confirm that it is still flagged "noindex".
And, yup, since the last time I looked, I've changed from +8% to -6%.
OK, this is clunky but I can't think of any other way to get the information.
Go to the Index Explorer page. Open every single directory on the list. (If there is an Open All button that I've overlooked, I am going to feel stupid.) Select the entire list. Paste into text editor.
:: pause for jaw dropping as I discover that this gives me, in one fell swoop, the full content of every popup on the page ::
Save. Now I've got something to compare to in a few days if the number is again different.
