Dave-to-Girl ratio

I was reading about Etsy's latest grant for women, and stumbled on the term "Dave-to-Girl ratio."  It's an old joke, but I laughed, and then realized that the Dave-to-Girl ratio for my research group was 2:1 (I count either Dave or David).  For the faculty in my department? 1:2.  The ratio is much better for the department as a whole, though.  What's the Dave-to-Girl ratio where you work?

Oh, and I just heard two IT guys out in the hall...one says to the other, "What about this one, Dave?"
