In a run with only three 277 drops, the odds that all 3 are Vanq is 6.4% (0.4^3). When you expand to runs getting 5 drops, the odds are higher still of getting at least 3 vanq tokens, though I’m too lazy to look up the formula for selecting 3 from 5.
But it would include multiple combos.
The point is we tend to misunderstand what those odds mean in reality. If you start with the question of what is “the odds this will happen to me?” 6.4% sounds low, but in reality it means out of every 1,000 runs netting three 277 tokens, 64 of them will have exactly this happen even if there isn’t an error.
And then those people show up to kvetch on the forums, somewhat understandably, from a personal pov.
Bit of a tangent, but it’s similar to how predictive scams work. You send 10,000 people a prediction that x will happen, and 10,000 people a prediction that y will happen. Regardless of whether x or y happens (you don’t ultimately care which) you then repeat the process with the pool where you guessed correctly.
It’s how you end up down the road with 10 people being really impressed that you predicted multiple outcomes in a row, when really all you did was cover all your bases and winnow the pool accordingly.
So the rationality error is really ours in misattribution of what probabilities represent, which is the likelihood of a certain outcome over a large number of cases rather than a predictor for an individual (my experience) case.
And I will say, I’m also in one of those raids that sees what feels like too many Vanqs, but in a scenario with only 5 drops possible, the law of large numbers plays out across the pool of raids, rather than within a raid.
Conversely, if a raid dropped 100 tokens per week per clear, there would still be some skewing, but most groups would see results much closer to the expected 40/30/30 split.
