User blog comment:DynamitMC/What the Drop Rates Actually Mean/@comment-26154973-20160220000428

Would be good to also have a piece on confidence intervals (like Akizuki on E-1 has 1%, but CI is actually 0.2% - 3%). The other obvious thing is that there maybe some Maruyus mixed in (or Mikumas, etc.), so to develop a farming strategy one need to add those rates to have a rate for target ship(s) + "ok, at least it's something" drops.
