1) Men are very aggressive, I would assume it needs to be something like 1:1.5 men:women ratio. But I do not have statistics. 2) Try it out with some market research! 3) Any sort of matching is going to fail if the data is not reliable. If I truthfully put 1.8m. Someone puts 1.9m when they're 1.7m. How do you determine that my input is true? Especially that since due to OkCupid, everyone is now automatically assuming the person is actually ~0.2m shorter. So if you put me and the other person together. The 1.9m person wins? 4) I can't tell if you have a plan for this. But a website that depends on a feedback loop seriously needs to overcome it somehow. Even PlentyOfFish for all the errors when I registered, I still tried to use it.
