Some values in a procedure are supposed to change every time, like mud weights, volumes or pressures calculated for a specific well or job. Those should not trigger a revision, since the procedure is doing exactly what it was designed to do. A real revision is when the method itself changes, meaning a step is wrong, missing, out of order or no longer matches the equipment.
For AI, that means treating calculated values as inputs to the job rather than content of the procedure, so it only flags a step when the instruction itself needs to change. Getting this right matters because a tool that flags every new number will bury reviewers in false alarms, and they will stop paying attention to the flags that are real.
