Tip what you want...

Whatever you feel is best to tip her if she goes over and beyond what you expected or you had an awesome time.No one knows that but you.
Any tip is appreciated never required so tip what you are comfortable with.
I always say the best tip is a return visit

Tips are really appreciated but never expected.  I agree that the best tip is a repeat visit or extending our time together.  But to answer your question, some guys tip an extra $20 and some tip twice the amount of the date, but the average for me is $100 tip.  Whatever it is I really appreciate it.  I even like when I get a hallmark card in the bathroom with my donation.  A lot of us are simple girls and just appreciate a good time )
