I don't see why this is any more likely to be true than "by giving ok but not perfect matches we lose two customers, but then they both come back after 6 months", or "by giving absolutely dreadful matches we convince two free-tier customers to pay" or "by giving perfect matches we gain 5 customers because they all tell their friends".
