Those are arbitrary too and as far as I know they almost never explicitly state a form is a "Final Form", at the most they just treat it like one in some arbitrary setting. For secondary Riders, that is. Main Riders' final forms are very official, as you can see by the Ridewatches.

They do seem to have some internal production logic that the forms they use as the "Strongest Form" are the strongest ones in the TV series but that doesn't mean we have to follow that. Toei/Bandai can be wrong sometimes, too. For example, the Para-DX Ridewatch being based on Perfect Knock Out Gamer as if it's his Main Form.
