Odds seem to be single digit percentage based on what I ' m reading on here and personally observed . If you haven ' t broken 100 Pidgeys you really haven ' t gotten to the point where you necessarily ought to have even seen a ditto yet . So all those people saying I ' ve caught 50 aren ' t even outliers yet . It ' s unfair that some people will see a ditto in the first hour while others won ' t see one in two days but those are the outliers at the two extremes and that ' s the fun of statistics . At least in this event the latter group will get a ton of XP and stardust . <| sep |> I actually caught a BMW using its blinker on camera <| sep |> You cannot discard the upgrades . You discard the entire card and buy a second one with the 3 point upgrades .
