The most accurate benefit of having a detailed procedure to follow is: "The more detailed your procedure is, the easier it will be for you to follow, and someone else, too!"
A detailed procedure provides clear instructions, which helps ensure consistency and reliability in carrying out the experiment. It aids in reducing errors, facilitates understanding, and allows others to replicate the experiment effectively. While a detailed procedure can also potentially lead to cost savings and improved efficiency, the primary advantage is the clarity and reproducibility it offers.
