I have a 1,400 page site which had pages going into supplemental around page 170 up until recently, when it went up to around page 330. I'd like to think this is due to me doing some general housework over the least few months, cleaning up code, shifting content location within the code, and tying up loose ends here and there. Am I right or does it have no relation? We've also added some new content recently but only a handful of pages, all unique.

I've also noticed that G is now listing the site pages in a lot more logical way, grouping them according to the type of page. Like it's "understanding" the site a bit better.
Fluctuations of IBLs to sites that are linking into sites linking into your site can have an impact. If they become more popular, IBLs to your site become stronger, and can change things even if you don't make any changes to your site and don't do any link building.
Trust level of your IBLs can be re-evaluated at any time too. If Google thinks your IBLs are more trustworthy, Google might attribute more value to them. That can result in more pages in the main index.
I guess this is the cause for less supplementals, presuming ODP links still count for as much as they used to...
