Butchery Efficiency

Butchery Efficiency is a stat: Multiplier on the amount of meat produced when butchering flesh animals. Its default value is 100%.

Factors

• Cooking: 75% plus 2.5% per skill level.
• Manipulation: 90% importance
• Sight: 40% importance, 100% max

A colonist with Cooking skill of 20, 2 bionic arms and 100% Sight efficiency will get 70% more meat and leather, this is because manipulation isn't capped while sight is, meaning that the higher the manipulation stat the more meat a colonist will be able to get from a dead animal or human. Since sight is capped at 100% efficiency it doesn't matter if the colonist has bionic eyes, the outcome will be the same, but if the colonist is missing one or both eyes then it will affect the butchering efficiency.
