hit rate

Hit rate, in a general context, refers to the percentage of successful outcomes or positive results out of all attempts made. For example, in search engines or caches, it indicates how often the system finds the needed information on the first try. In business or sports, it can measure how often a tactic or player achieves the desired result. Essentially, it quantifies efficiency or effectiveness—higher hit rates mean more successes relative to attempts, helping evaluate performance or the quality of the system or strategy.
