Holy shit. I'm officially convinced that the shiny charm stacks with masuda method. I was working on completing my living pokedex, and I breed 5 eggs at a time, and hatch all of them at once. I got 2 shiny pokemon out of the 5 eggs with me...a shiny shinx and a shiny kricketot. If my math is in right, that's a 2/(1024^5) chance, or .0000000000000000776% chance. Kricketot looks decent, but I really like the shinx (and future luxray)~
