The over arching rule is that 200 basically identical cars need to be sold in the 12 month period.
First part says that 50% of the required number needs to have the different ratios or number of gears.
The next part says that this is not a requirement for the Australian 200.
So, going by that alone, a single car could be fitted with different ratios or number of gears and still be eligible.
There is no 300 or 400 mentioned there, so have no idea why you even bothered to include it.
Seems you are trying to make up rules to suit some sort of agenda.

Rob that 50% rule only pertains to gearboxes with a different number of ratios and different in their staging. ie:a 3spd and a 4spd, and as you stated it was not applicable to the Australian made 200 cars in any case.
There is no 50% rule for two gearboxes with the same number of ratios and different in their staging and there is no 50% rule for diff ratios.
Up to the end of 1971 Group E it was left totally up to the manufacturer to decide how many of the minimum production received which gearbox (if two options were offered to the purchaser) and which final drive ratio (if two options were offered to the purchaser).
The following addition to the 1971 FIA Group 1 Series production rules sums up the intent of the FIA Transmission regulation very nicely. A regulation that the CAMS copied virtually word for word and used in their Group E regulations up to the end of 1971.

Simply replace 5000 with '200 Australian'
As we can see that is exactly what Ford did with the XW GTHO Phase II. The minimum production and sale of 200 cars were recognised in accordance with the specifications of the recognition documents.
Two gearboxes with the same number of ratios but different in their staging and two final drive ratios.
