Sorry to say, no such mathematical formula was used. Lots of guesstimating! I guess it's a little misleading that the chart is called a "Precise" Sizing Chart, derp. But basically, we have an average range for each form and tried to correlate "small" in Lupus with "small" in Secui and Optime, if that makes sense.
