A while back I saw a post by nonnipoppy for cache stats software from Logicweave.com.
I liked the stats and have been using them on my profile.
I came across another site ItsNotAboutTheNumbers that will give you several stats and several different types of maps. There is an html feature that will allow you to copy and paste stats to your profile, but some of the maps you have to save and then put them as an image on your page.
I just wanted to pass it along....
