In other words, while this doesn't yield you Item ZY 100% of the time, it's a high enough percentage that players will gravitate towards that formula in order to narrow down to specific items they want produced.
Ahh good to know if I ever decide to pick the game back up. Right now it's not my cup of tea so to speak.
