How the calculation works

allocate ends proportionally; distribute rounding remainders to the largest fractions; yarn = ends × winding length

This answers how much of each color to buy. It does not specify stripe order or preserve a color repeat. Ties are resolved A, then B, then C. Whole-package rounding should be done for each color separately.

Full calculation methodology

Worked example

240 ends at a 2:1:1 ratio become 120, 60, and 60 ends. At 3.5 yd per end, that is 420, 210, and 210 yd before reserve.
