This talk page is for discussing the Calculator:Barrows page.

Calculator is incorrect[edit source]

It's pretty blatantly wrong. It gives the chance of getting a barrows item from a single chest as 1/14.57, when it's really around 1/15.01. Simply do (1-24/2448)^7 to get the real droprate.

This calculator is not meant to compute the probability of getting at least one Barrows item. Like the rest of the calculator (e.g. the runes), it's computing the expected number of Barrows items you get. That number is 7*24/2448, or 1/14.57.ʞooɔ 02:17, 2 May 2020 (UTC)
