OK, I think we're fully in agreement here, modulo terminology. You are using "true positive" to mean that the watch correctly predicted a positive score on the medical test. And these are the people who may be treated, some of them unnecessarily.

The problem is that we don't know what to do with that data, which is different from the test making a mistake. There are other situations where it actually is a huge problem that the test makes a mistake some percent of the time. It's important to distinguish the two problems.
