[ORAS] Proven (not confirmed) way to Shiny Chain using DexNav!

[Joushou]

Seems like the 20 steps isn't necessary. I'm not even moving after the encounter before starting a new one. Sometimes the search will fail and I'm still not sure why. This happens both in grass and out of grass so I'm not sure how the game is deciding to break the chain. I've also caught the chained Pokemon and had my chain continue afterward but running WILL break the chain always. One thing I'd like to point out also is that if you walk out of the grass before pressing search you run the risk of a random Pokemon appearing on the DexNav and breaking the chain (even if it is the Pokemon you are looking for). This can also happen in the grass which is why I usually press search right away after I faint a Pokemon in the chain. I really want to know what causes the random chain breaking...
