Square-1 Parity Fix

I do not have a set algorithm for the parity fix I use. Just go to 44 / 44, swap 3 pieces on top with 3 on bottom, go back to cube shape and resolve then finish solving the colors. I noticed one day though that sometimes when I get back to cube shape all the correct colors are on top, but usually not. So today I set out to discover and document how to fix parity with a minimum of damage to the solve. Found it. When you make the swap of 3 pieces make sure you move the same number of yellows down that you move up. For example:

/ (3,3) / (–1,–2) / (–2,4) / backtrack

goes from solved to
