Feel the need to respond to the math debate in this thread.

Firstly you are right. If the drop rate for atma is 1% then you have a 1% chance to get an atma after every fate irregardless if you have done fates prior or not.

HOWEVER. If you look at it as a series rather than individual events you can look at the probabilities as a whole. Example if you are to commit to doing 500 fates irregardless if you get an atma or not your chances of not receiving at least 1 atma across that series is 0.6% (0.99^500). AKA very very low

Of course no one will do 500 fates irregardless of if they get an atma or not. They will stop once they receive their atma so the above example is not an accurate one.

Really what you need to do is use survival analysis. My survival analysis is a bit rusty but using an exponential model I estimate the half life of atma farming would be roughly 70 fates.

So while yes you can do 500+ fates and not receive an atma the fact is that's a very unlikely outlier scenario
