Driver Tagging & How it works??

I was looking for more details on how driver tagging works.  I understand the basic concept but where theres a gray area is does DeployAnywhere still complete its scoring system to select drivers as well as your tagged drivers or just your tagged drivers?

Reason I ask this is many mondels generally utilize the same driver, so instead of uploading the driver multiple times but just with a different tagged name, I just have to upload it once with no tag.  Then just tag the drivers that are model specific.

Any insight would be greatly appriciated, thanks!
