Well, this method is highly dependant on rune prices, which fluctuate a lot. As a result, sometimes this script is very profitable, and other times it is mediocre at best. Often when the OSRS team release content which drops valuable runes (e.g kebos, raids, slayer bosses, zeah, ...) the price of said runes drops so margins with this script change. It is worth doing a test run and/or rune price calculations before investing into this script
