regular: 400 = 83
bold: 700 = 151

(700 - 400) = (151 - 83) 
300 = 68

400 * .75 = 300

diff = 400 - 300 = 100 

1 / .75 = 1.333

Regular font has a stem width of 83 units.
if it gets scaled down by 75% the stem is now only 83 * .75 = 62.25 units.
we need to compensate that missing 20.75 (83 - 62.25) units on a scaled factor (20.75 / .75) 27.66666667

if we raise the font-weight unit by one we gain the following units:
(151 - 83) / (700 - 400) = 0.22666667 units

how mani font-weight units are needed to get the same stem width as regular font?

27.66666667 / 0.22666667 = 122.05882175 units

new font-weight unit = 400 + 122.05882175 = 522.05882353

formula: 
400 + ((83 - (83 * .75)) / .75) / ((151 - 83) / (700 - 400))
