Just thought I'd help. :)
To get accurate IV's, people will do Wifi battles, then Write down the stats of their pokemon, without actually battling. This helps if you want to pick out the strongest pokemon from a batch of newly hatched eggs. Since in wifi battles set your pokemon at lv 100 automaticly for the duration of the battle.
