Conflicting info on converting existing gold subscription to game pass ultimate

I am considering upgrading my Xbox live gold membership to Xbox game pass ultimate. In your information here https://www.xbox.com/en-US/xbox-game-pass , I see it says that I can convert up to 36 months of gold to 36 months of game pass ultimate. However
it also says in a different FAQ questions that my gold would be converted to game pass ultimate using a conversion ratio, which would mean that I would get less than 36 months of game pass from my 36 months of gold. These are conflicting statements, so which
one is true?
