Numeric System for Firmness

Hi again! Thank you for all the encouragement and support. Have you guys considered creating a numeric system for the stiffness of cups? Like, ranging from 1-10? It could be something even menstrual cup manufacturers may start using on a whole, so as to let their customers know the firmness of their cups, in relation to other cups. It also makes it easier for some1 who may not have a perfect cup (but it's almost perfect) in terms of stiffness, to decide on their Goldilocks cup.
