I classify plain buck/doe urine as a curiosity/calming scent. I mostly use it if I know deer are moving through the area. I don't expect it to pull deer towards me. The deer will be curious as to who the "new guy" is. If you have an active scrape it can freshen it up!
I've urinated in deer scrapes myself on purpose. When the competition is on those big bucks don't like to be outdone!
