The phrase "high degree of consistency" refers to a level or standard that is very uniform, predictable and reliable. It means that something is done in such a way that it remains consistent over time, with little variation from one instance to another. In other words, there's an expectation that the outcome will be similar each time, regardless of any changes in circumstances or conditions. This phrase can be used to describe anything from personal habits and behaviors to larger systems and processes, where a high level of accuracy, precision, or quality is desired.
