Wonder if 0 can be included. It doesn't fuck up the 325 total.
Here's a table somebody posted in the crewmate thread.
What we don't know is the category of Zoan. Clearly Inu (Dog) doesn't work by itself, as it technically is 1 (I), 2 (Nu). Okami (wolf) doesn't either, as it's 0 (O), 5 (Ka), and 3 (Mi)
If you try Ooguchi, you get 2 of the 3 numbers: 0
(O/Oo), 9
(Gu), 7 (Chi). Makami does not work at all as far as I can tell.
So at this point we need to know the Zoan category is (Inu/Okami/or even something else, remember Kaido is a fucking fish lmao), or if somebody more experienced could make more sense of the fruit name accociated available Numbers. It's possible this table does not represent everything, or represents things inaccurately.
It's also possible that this number theory doesn't even matter anymore or disqualifies Yamato in general
