I did this a little bit ago, and it really has helps find women who will be interested in replying and meeting up. It helped me narrow them down using the search feature.

I simply made spreadsheet listing all the women I've had sex from online, then averaged out the numbers.

The data I used was:
- Age
- Height
- Smoking habits
- Drinking habits
- skilled / unskilled/ semi skilled work skills (20K and under unskilled / semi skilled 30K - 40K / skilled 40K and up)
- does she have children?
- Distance from me

After doing this, I found almost all of them hit around the same height, age, had the same smoking and drinking habits, and job skills.

It might save some time from mass sending a bunch messages.
