Let this post play out for a couple more days and you'll see the set up times decline. If someone says it takes them 17 minutes, the next person will be inclined to write that it takes him 15, the next person may be 13 minutes and so on... That being written, there are some serious professionals here and I don't doubt for a second that some folks can fly up some trees. Experience plays a huge role in this, gear does too to a lesser extent.
My goal is to get into hunting position as quickly and safely as possible, but I consider being set up quietly a higher priority for me personally. I have climbed some trees with (3x) LW sticks and aiders in some pretty fast times, but my favorite climb to date was a time that I had a small buck standing in the dark at the base of my tree sniffing the aider on my bottom stick while I was standing on the middle step of my top stick - that was a cool morning experience, one that I wouldn't have had if I made a ton of noise climbing that tree.
I'm writing this just to say that if you are basing your query on climbing times to satisfy a curiosity of what other folks do - good on you. If you are asking your question to judge yourself and end up pushing your limits in an unsafe manner or ruin your odds of shooting your deer - shame on you! (sarcasm inserted for emphasis because most days I'm happy just to not fall out of the tree...)
