My browsers are all set to dump cache and cookies upon exit.

I'd be interested to see if this has changed much in the almost 7 years since that study was done.

It depends on how much the browser caches have grown to compensate for page bloat. Ie8 and below had a limit of 50 mb for all sites, ie9 upped it to 250 mb.
