My thought is you should post the stats of the lady whose web page is linked to the review or who is more prominently showcased on the linked web page. Unless your review is the first one for the ladies, your stat entries won’t change what is displayed with the review anyway, so pick one and go with it. In the details of the review you can always provide your take on the looks and attributes of each of them.

It's not a perfect system - it just is what is it. You can always try and get it changed via a request on the Suggestion & Policy board.

If you've seen and reviewed both girls individually, can review them again as a double?

Indicate that in each review, that you saw her with the other woman you saw as part of a doubles match.  Describe what happened with the both of them in general in each review, then emphasize specifics on each woman in their individual review.
