To me the fact that utg cbettor is a whale and that the size of the cbet is 1/5th pot is way more relevant than the small sample low 3b/nit stats.

If I'm button I'm raising every 9x/Tx/QJ/KQ/KJ/any overpair cause based on sizing it's pretty clear the whale has nonsense. Whether or not btn is aggro loose enough for that is clearly up to debate based on the number of hands. But if we think he's looser more aggro than his stats then I do think those hands above are possible and if his stats are representative I think more overpairs are possible.
