For the A6M5 Zero you change it to the A6M3 Zero which is fair enough as with the other factory you have 2 x 30 R&D. Is the thinking here that you will just change the factories over to the new models on their standard arrival dates and that it is more important to have the A6M3 early than the A6M5?
No, my thinking is that once the M3 R&D factories are fully repaired, I'll move them up the line ASAP.
I think i am missing your point here - isn't the A6M5 already further up the line?
Also - is it worth rushing the Sen Baku (which is the upgrade to the A6M2) as it upgrades to the A6M5b and i'm assuming there will be a large number of the old A6M2 still around?
There is no damage or cost associated with moving a fully repaired R&D facility to the next upgrade option as defined by the editor. The advantage with non-realistic is that fully repaired production plants can be moved along this path at no cost too.
Which is why building the A6M2, and then switching it to the Baku and then the M5b is a good option for non-realistic(straight away), but can’t be achieved with realistic R&D.
So what I'm saying is don't research the Baku, playing Realistic Off - build a few more M2 factories, when fully repaired, switch them to the Baku and in the same turn, to the M5b and voila - you're researching that! Can get it a year early if wanted.
Implication here is (if i understand you correctly) that the Baku is not that important and not needed early whereas the 5b is a better option.
As a result it seems you can get the 5b earlier than the Baku even though the Baku won't have finished R&Ding and the 5b comes after the Baku. This seems odd.
Finally, when you say switch them in the same turn - does it have to be the same turn? e.g. if you forget to do it on the same turn can you still do it the following day>
