Yep glad to have more evidence.

Anecdotally my identity did shift around that age going from nonbinary to binary female, and it was largely related to allowing myself to accept myself, experimenting with identities, and self reflection. Getting to hormones was extremely difficult.

And I do know someone who went from identifying as a binary man and taking T to nonbinary and not taking it. They're still glad they took it long enough to have some voice and hair changes, they just didn't like the emotional changes. They later got top surgery and were very glad to do so.
