Do you directly use the PWR guideline or has it been proceduralized?

Good Afternoon all,
We recently had a discussion on site about how to grade a reactivity management legacy issue in a calculation.
Does your site have any guidance on how you would grade a legacy issue, such as:
Would you grade it in RM space if it is a calculation that is still in effect? Yes
If the document is beyond a certain age, would that change the grading? If document was removed from use at least a year before implementation of the industry standard RM PI, it would not affect the PI. The industry standard RM PI guidance removes deductions from the current PI one year after an issue has been resolved.
If the document had been in use, was removed from use, then the error discovered, would you grade it in RM space? Yes (See response to question 2 above).
Thank you in advance.
