Eh, I'd question that.
At the end of last year, Suyin was Late/Mid. We were Late/Late by Week 24, and it then took us ~2 months before we were arguably "ready" to potentially begin breakthrough (though we went and dragged things out longer).
As a rough estimate, Suyin is taking around twice as long as us.
Now, yrsillar did say on discord that if she wasn't going on the expedition with us she'd probably be working on preparing for breakthrough etc., so from that we can infer that she isn't finished that yet. It is perhaps plausible that she might be ready to start working on her Green breakthrough around Month 4 or 5. Given that she won't have hax drugs like we did, she probably won't blow it away as fast as we did. A month at least for Green is probably fairly plausible? Given her issues around physical, Bronze is likely to take longer. Probably several months at least if we take Xiulan as a guide (and she's still more physical than Suyin and was getting to use the White Room).
So, if Suyin does well then maybe Green around the middle of the year, and Bronze nearer the end, maybe around Month 10?
This would also be consistent with the way the yrsillar has generally portrayed cultivation progression, with most people failing to get to Green in their second year, and even lots of Inner Sect disciples only just getting it in a year.
