In this task, you're given passages that contain mentions of a time duration related quesry and we are supposed to write answer to a question that involves event “frequency", which refers to how often an event is likely to be repeated. For example, "taking showers" typically occurs ~5 times a week, "going to saturday market" usually happens every few weeks/months, etc. 
 Note that a lot of the questions could have more than one correct answers. We only need a single most-likely answer. Please try to keep your "answer" as simple as possible. Concise and simple "answer" is preferred over those complex and verbose ones.  

Q: Sentence: Illegal pinning methods include using the ropes for leverage and hooking the opponent's clothing, which are therefore popular cheating methods for heels, unless certain stipulations make such an advantage legal. Such pins as these are rarely seen by the referee (as they have to see if their shoulders are down) and are subsequently often used by heels and on occasion by cheating faces to win matches. Even if it is noticed, it is rare for such an attempt to result in a disqualification (see below), and instead it simply results in nullification of the pin attempt, so the heel wrestler rarely has anything to lose for trying it, anyway. 
Question: How often are illegal pinning methods seen by the referee?

A: Such pins as these are rarely seen by the referee
