I remember sharing it with my partner who is in a less common cohort and had done plenty of research prior to my sharing this with them... they were not at all impressed and felt like there was something lacking in their methodology and priors.
Specifically, my partner has found that the most consistent and predictable sizings are from the UK -- everything else is more all over the place and must be tested on a per brand and pattern basis.
The post by A Bra Theory states it can take as many as 9 attempts with their system to achieve a fit.
With US sizes and her proper measurements, it can take 3-4 attempts for my partner to find something that fits or determine that they do not carry anything that will. With UK sizes and her proper measurements, there is typically success within 1-2 iterations.

I find it strange that in the past nor in the present the Bra Theory hasn't seemed to lean on A Bra That Fits or the UK sizings and patterns.
