Define predictable in your own words, @dylan23. I see how it's different from consistent, but why does that split matter in this case? Give an example of something that's predictable but not consistent. Linking to the_amy's point, can a result be both surprising and predictable at the same time? I'm just trying to peel back the layers on your original comment.
You said "consistent results" but like dylan23 was getting at, that just means it works the same way every time. I mean, is an AI coach really that different from just having discipline? Maybe it's just me but idk if we need an app for everything, even if it works.
