You don't understand the problem the parent commenter is talking about. This isn't about who is or isn't successful, it's about incentive structures, and the degree to which dating service providers have an interest in having more or less people find love. Currently, people finding partners and being happy means that dating service providers lose money, which means that they will deliberately show you partners that are less interesting to you, to make sure you keep feeling unhappy and come back to the app for another try.

Your experience actually corroborates this, as most people do not want to do a lot of serial dating, and your advice is all about serial dating.
