“something becomes a problem after you systematically test it iterate on the results and try many different ways from let's say radical to iterative and you're still stuck at the same level then I think I can consider that as a potential problem”

A metric is just a fact until systematic iteration proves it a problem

A 5% install-to-trial rate (vs. a 15–20% benchmark) is not a problem — it is a fact until you have exhausted both radical and iterative approaches and are still stuck. Labeling something broken after one attempt, like $5k on Snapchat for a week, is premature diagnosis that blocks real learning.
