Final answer:

The exact timeframe for sending a PIM to the regular reporting senior is not provided in the question or the reference given. It's necessary to consult the specific guidelines for the correct answer as the provided forty-five days average time does not match the options listed.

Explanation:

When sending a Performance Information Memorandum (PIM) to the regular reporting senior, one must ensure that it is done within the stipulated timeframe. Although the question does not provide specific context regarding which rules or guidelines are being referred to, it is important to follow the designated protocols.

The options given in the question are 10, 15, 20, or 30 days, but without the correct context or reference, providing a definitive answer is not possible. The reference provided regarding average times, which mentions forty-five days, does not directly relate to the times listed in the question. Thus, it's essential to check the relevant instruction or manual for the exact timeframe to submit a PIM to a reporting senior. Contextual accuracy is critical in following procedural guidelines.
