Things are definitely not static in my life- my winters vary a lot year to year, my weight fluctuates, my work and hobby activities change. And I had quite a lot of churn, which made my tracking sheets messy so I had to keep rewriting.
I was mainly just looking for what was constant, the Real essentials, and to see if my wardrobe category numbers were good, or if they should be lower. Plus I wanted to get an idea of how quickly things wear out and where it was worth spending more or less money.

The 5PF is sort of seperate from that, it's to slow the churn and be more mindful, stop automatically buying duplicates in different colors, and move to a simpler and essentials focused wardrobe.
