Well with that rarity rating, there are 3.5 women for you on the planet currently. You have a chance at meeting about 0.01% of the total human population in your lifetime, and thats only if you travel to every big city on the planet and spend some time traveling everywhere in it. About 45% of the worlds population lives in rural areas however, so you will probably only meet about 0.05% of the women out there who are perfect for you in an extraordinary lifetime.
