Well you get skimmed milk > whole milk, and single cream > double cream, so it seemed pretty logical to me to compare the % thickness of cream to % thickness of women (eg. her milkshake so thick it's butter, it brings all the palaeolithic boys to the yard). I don't think Mal's measurements have changed that significantly to update anything, plus the last couple of times she missed her thigh circumference, and her bra size is out of date because it's been years since she used the 'ABraThatFits' method. Mal's still at her highest thickness of at least 137 though (previous highest was June 2020 of 132), which places her as thick as butter, which has been the case post 220lbs.
