Just to throw it out there, there are a few useful tips found hidden in the pages of this thread that were not in the guide. Such as a picture of the grid, much helpful, and also knowing that the grid moves when you do. At first I thought the grid remained solid, and the Y factor (you) was only in reference to when you restarted the radar. =P
Despite my best attempts and the advice from both the guide, this thread, and a friend, I have a hard time getting above 25. I go extra careful after I hit about 15 in the chain but always seem to miscount or not recognize a good/bad grid pattern. Meh. I get frustrated after a few chain breaks and give up. I salute those who can sit and chain for days.
After starting a chain with a pokeradar pokemon only, are the chances of it breaking greater, even when following the guide?
