there's actually a lot of data on elite women available -- you just need to know where to look! and with the advent of on-board power meters, coaches are able to collect data from a wide range of clients.
hopefully this chart will answer your questions (developed by power guru andy coggan).
btw, a straight watts number won't give you much information. what you want to compare is power-to-weight ratio (ie watts/kg of body weight).
ps -- if you have specific questions about this, please email me off-line as I'm not hanging around TE much these days. I'm happy to share my knowledge if folks are interested.
