Here is a huge problem I always have with Pokewalker:
>I make 5.000-10.000 steps on Pokewalker.
>I go to Poke Radar to catch some rare Pokemon that appears on bushes with 3 or 4 exclamation marks.
>Instead almost all the times only common Pokemon at bushes with 1-2 exclamation marks appear.
I know that it's all about timing but I'm either too early (I choose 1-2 exclamation mark bush and a common Pokemon pops out) or too late (the Pokemon gets away and I have to start over again). Is it indeed all about timing? If so, which exactly is the right timing? Or there is another trick? That's why I have never caught any Flying or Surfing Pikachu yet. Everybody with a Pokewalker have them except me and it sucks.
