My take: a month is about the minimum before judging any platform — it is the single change that made the most difference. What is the cost of a match dating service compared to other sites?
In my experience, taking a break when it starts to feel like admin is sensible — it took me longer than it should have to work that out.
A platform's age tells you something, but not much — nobody tells you this at the start.
Speaking generally, consistency matters more than intensity here — others here may have had a different experience.
