I use sort of the same way to score my 7 views on the ad-carousel as quickly as possible.
It's the loading of the pages that takes longest. Your trick of opening in new tabs skips this wait (for you can continue working the list). I can imagine this is the best work around available.
It can't be very hard for wgt to implement a more user friendly method, but hey, who am I to say so, right ?
