Writing a chart of the prayers and marking each prayer in which he caught the opening takbir: Is this self-accounting?

Question:
He says: Honorable Shaykh, may Allah grant you success. If a man puts down a piece of paper and writes a chart of the prayers, and whether he caught the opening takbir, so that whenever he catches the takbir for a specific prayer he puts a mark, and he reviews this on a weekly basis, and his intention is to hasten in good and to hold himself to account, is this action prescribed?

Answer:
This is an over-exertion. This is an over-exertion for which Allah has not sent down any authority. He should strive to be diligent, to strive to be prompt and to race to the prayer. He should not count them. Even in this, he is holding himself to account. Allah the Exalted holds people to account for their deeds. What is the benefit of this? Yes.
