Pro Sites: Auto generated pages

So im working on a clients site and everything is breaking in regards to pro-sites. I start figuring out that he has deleted the checkout pages that have been auto generated. So i take a look in the trash and I find 246 pages deleted. lots of different pages called checkout, cart, account etc etc.. seems like the client tried woocommerce wp e-commerce and other plugins that auto generated pages plus made some of his own, then put every page in the trash can, including all generated by pro-sites...
so i need to do a head count after this rescue operation..

so, how many pages are auto generated on plugin activation in pro-sites? if the auto-generated page(s) are deleted from the trash, and the plugin deactivated, re-activated, will they be re-generated, or has the plugin got a first-time-activate check inside its register_activation_hook?
most importantly, and simply, how many pages?
