I have 5% all the way around and my whole windshield is 35%. I'm guessing that something similar to what BrianBrave has because it looks like his windshield is tinted too. Also I'm pretty sure the windows come 70% from the factory, so you would have to take that into consideration. This means if you put 5% over that it would really be 3.5%. I've been pulled over many times and the tool they use has said anywhere from 2% to 4%, although this is very illegal in New York I was burned badley and have skin graphs so I "can't be in the sun", and I have a sticker from the DMV that allows me to have whatever tint I want. Anyway just go with what you think looks best and what you're willing to deal with for visibilty at night. Good Luck!
