WagStays is a platform to connect pet owners with pet care-givers near them. A user can find and book them through our platform. We've been trying to understand where we stand in terms of product market fit and Sean Ellis' test is good, however one of the criteria of selecting the user is someone "who has used to product at least twice". Most of our users have the need to use our services 3-4 times a year. In such situations, how do we accurately use Sean Ellis' test to arrive at the most accurate results?
