I'm pretty good at UX and I don't have any issues with the current experience. It actually really helped me for my use case.

Your mistake is thinking the purpose of the app is to give the user the perfect objective recommendation. For most decisions, you just want some kind of psychological justification - for some people that can even be a coin flip.
