Well you explained nicely, still the thing I meant with limit is, the quantity and the rate at which a user can produce his element. I mean it is near limitless but there has to be a range and rate factor. Also Oda only made a joke about that thing of 200 Gomu Gomu or Hana Hana, he was not serious and I know Oda said that some scientist will debut and explain the devil fruits (possibly Vegapunk???). As to what Pell said, I think h meant it this way, all Tori Tori no mi is one category, (that means Marco and possibly Laffitte are also in his category). Same ways the Logia (if their ability could be considered flying) is another category, Shiki takes another with his power, then you still have two more left (although Laffitte may not have a Tori Tori no mi and in my opinion, Robin is not counted as her ability is derived).
