"Anyone having really bad luck getting shiny ghosts?"

#PokemonGO: I am having some awful luck trying to get a shiny. I am on 585 sableye seen and 320 duskull since they were announced being shiny and 3 dusclops and still no shiny. Most people I know who have shinies have got them at less than 100 seen for sableye. Anyone else experiencing the same bad luck? Edit Supposedly it is 1 in 256 chance of finding one, though my findings defy these odds via /r/TheSilphRoad http://ift.tt/2iKDE8Z
