No formula, just careful study.
Mary knew she had to go through the purification rites and the priests of the day knew that fact.
Agreed.
Nothing in the scriptures say that she was exempt because of some miraculous "get out of impurity" card.
That is an argument from silence.
The scriptures do say over and over again that Jesus was sinless so to compare the necessity of His baptism to Mary's purification is comparing apples and oranges. They are inapposite.
That begs the question.

No, that's what's called a reasonable inference from the facts.
"The scriptures do say over and over again that Jesus was sinless so to compare the necessity of His baptism to Mary's purification is comparing apples and oranges. They are inapposite."

No, I cited the scriptural references to Jesus' sinlessness in previous posts and the scripture for the necessity for the purification rites so this is a inference drawn from facts outside the conclusion.
