To photoprism users: do you know how well it handles identifying photos of kids over the span of years?

Google photos absolutely blows me away with its ~1% false positive rate (that is, given a photo, correctly identifying with kid(s) are in it) identifying each of my kids, nieces, and nephews. I don’t really know what its false negative rate (a false negative would be an uploaded photo of John but that doesn’t get tagged as having John in it) is, though.

I can search for each of my kids and see photos of them going back to their birth.
