Well, if they did understand, they would say the chance is ~1 in 2^61, not 1 in 2^122, and they would've based the math comparison to RAM failure on 2^61, which changes the comparison entirely. In any case, I should have been more clear. I'm not necessarily worried about this case. But if you design systems and miss a factor of a square root, you tend to break things that we're all relying on to work.
