I'm at least mostly positive I'm doing everything right here but my luck is awful. I'm sitting at about 9 hours shiny hunting this Latias over 3 days with nothing. Got a lvl 3 sparkling dragon donut, running the route from the building corner to the second bush to spawn/despawn, and my hard save is outside the spawn zone and still can't find that golden girl. Being conservative it's about 240 checks per hour, that's about three times over odds even if I was using a lvl 2 donut. Anyone else having rough hunting?
