Welcome to the Q&A Forum

To Ben's point, it's not just sanity you'll be saving.  You'll be saving your site from multiple pages cannibalizing each others ranking strength.  It's much healthier to group them together as long as each individual topic is truly very near identical to others.

Crawling the web can be complex and problems can pop up like they did this month. We are working to increase the speed at which we release updates and this crawl we ran into a problem that forced us to start over, hence the longer delay.  Otherwise it was going to be out on the 11th of July.  Sorry for the delay.
