I think that would be a statistical mistake to cherry-pick the cutoff like that. What would be the argument for ignoring the X months/years beforehand in which no one died?
If I asked you for the odds of the next three coin tosses being heads, you don't start counting on the first heads. The first toss being tails is a possible outcome that can't be ignored.
That is an excellent point. Maybe the math has to be using the average length of time the whistleblowers have been 'out' as it were. That could plausibly end up being several years, which pushes the 1:32 number a lot closer to 'certain' and the 2:32 number way up into entirely plausible.
the deaths happened in two months. not in the space of a year. you need to take that in account.
