I checked my average delays by going in on Time finder --> Capture --> method 5. Then I checked the IV's of captured Virizions and found the seed and clicked on "generate more times" to see the delay ^^ My delays varied a lot, usually between 880-920 so thats why it was such a pain to hit the right seed O.o
Hm, okay^^ But I probably gonna stick to captured mons for now xD
