>>27230485This is just from my experience, but pokemon spawn based on the traffic of pokemon go players that catch things/use the nearby pokestops. Thats why no mans lands have shit catch pools. CP of pokemon is based on your level and the level of others playing in that area before, in level 22 and when i put up lure, my level 16 friend and i both find similar cp pokemon at my cp level 0-400 pidgey. You will still encounter crap but the ceiling increases with each level and so does the cp gain from evolution. Nothing is confirmed but this is my observations
