Initial reruns have consistently happened 3 patches after the initial banner exactly...so far. HOWEVER, one of our recent patches was a double new doll release (Springfield and Peri) and historically double-unit patches have rerun their units over two patches, not one.
This implies that Springfield and Peri may rerun during different patches, which would delay Qiuhua's rerun.
On the other hand, a single patch featuring two limited dolls has happened exactly ONCE before, they were literally the first limiteds that were ever released (Suomi and Ullrid) and this happened before a lot of other relevant systems were put into the game like the special 'selector' banner that lets you choose from a set of past dolls.
So, things are very different now than they were back when Suomi/Ullrid reran.
On the OTHER OTHER hand, Springfield and Peri's event was originally a 2-patch event on CN. This event was just given a truncated release schedule for Global because they wanted to speed it up - but this doesn't necessarily give it special status as that's exactly what happened to Soujourns of the Glass Island (Ullrid and Suomi's event). Conversely, Klukai and Mechty, whose event followed a similar structure but was not truncated, DID rerun separately and quite recently at that. So, eh, points for and against basically.
Anyway that was a whole lot of yapping to basically say; if Springfield and Peri rerun together, you'll only be waiting 3 patches. If they rerun separately, it'll be 4. Impossible to say which at this stage (but it's fun to speculate).
