Well I tested myself in getting a wild shiny. And it usually takes me 2-3 tries to get it, but I can. But when I start going for specific IVs I never hit the delay. Pikatimer settings are the same, 600 and 14 calibrated. Though it feels like the delay I get changes. I'll spam A to get through the screens and still get different delays. Is that just luck? Should I just keep doing that until I hit the right delay? That's what worked previously, but I dont know how Id hit any delay over 610.
