I am not aware of the adjustments they made after the bad mulberry fiasco. There are factors, methods, and ways in which it is entirely possible for 2 complete consecutive production runs. 15 week egg rotation easily nets you 2 consecutive complete 6 week production runs.
It is very possible you know more than me on how they adjusted, but enough time has certainly past to enable 2 complete runs. It is protocol dependent.
Maybe they constantly keep several production runs in refrigeration. I do not know how they handled it, and I don't need to. But time isn't the issue there if they did production differently. It is possible.
