Like, for sure good at that point. I'd say. I'm not an expert on hacking so I don't know at what point the security breaks down, but it's below that point.

So there is actually a LOT of tolerance for unfair dice in the entropy generation. You can even use a die that shows the same side side half the time (so like p(1)=0.5, p(2)=0.25, p(3)=0.125,...), do 99 rolls of it, and have an effective entropy of roughly 192 bits (vs 256 for a Vegas quality die). ...
