I never said it was a fact, did I? I said he went looking for the Androids when he was activated, which is stated. If he went searching for them, then it means he was confident taking on both of them like he was after absorbing over a hundred thousand humans in the present. One points to him needing that amount, the other seemingly doesn't.
I'm not focused on how they scale. We're told there's simply less opportunity for him to gain power akin to what the other Cell did, so it wouldn't factor into anything.
