If something is not defined in the FARs, then it is a kind of a grey area and different FSDOs will give you different answers.
The definitive answer can come only from the FAA Chief Counsel, and a website with those rulings is
here.
There is a whole load of obscure stuff which is not defined in the FARs, especially involving obscure aspects of training and flight experience outside the USA.
The bottom line in practice is that if the DPE accepts something, does the checkride, and signs your certificate, then you are done and you move forward from there.
You need to speak to the
actual DPE who you will be working with and check this with him.
