"All OkCupid users create their own matching algorithms, so when we determine who matches who, we’re just crunching the numbers people give us."

Aspects like age/location can be included as part of the user matching algorithms if it is important to them. Overweight/has kids/ugly should be equally spread out between races and should not be dependent on race, especially only after the first message.

Therefore match % is basically everything except race that is important to the user.
