Thats the thing, using the Masuda Method(breeding two Pokemon from different countries) doesnt have a chain. The chances are increased yes, but its not like Pokeradar in terms of chaining where each Pokemon you encounter in a chain raises your chance for a shiny to appear but rather than all Pokemon hatched from those eggs have increased chance to be shiny, even if its your first egg from those two. While the standard encounter rate for a Shiny Pokémon (either in the wild or by breeding) is 1/8192, the Masuda method multiplies this rate by 5 (to 5/8192 or about 1/1638) in Generation IV and by 6 (to 3/4096 or about 1/1365) in Generation V for all eggs. We dont know the exact value for Generation VI or if it even changed from Generation V.
