How it reads your answers

Your stage and your worry pick the reading: flat adoption before launch is a different problem from flat adoption at scale. Team size and what being wrong would cost give the number, with the formula next to it. Some answers only mean something together, such as little evidence answered with more features, and the check says so when it sees them.

The last part is whether a second look is worth it. It depends on what is at stake, how much of the plan comes from users, and whether one person can make the call. When a test you can run yourself is enough, the check says that.

Nothing you type is stored or sent. The page records only that a check was started and which area and reading it ended on.
