I am using Sandshrew atm (female has my OT, male has OT of another random player. Non masuda method)You should be able to establish a pattern after only a few, but obviously the more you use the more certain you'll be. If you wouldn't mind posting your seed info and the info of the mons you're using to verify your seed, I'll take a look. Ideally I'd be able to recreate your scenario on my end, so anything and everything you think would be good to have.
Male is in Dream ball and female in Poke ball.
No HA, so ability can be either 1 or 2, but I dont think it matter much?
The seed you see here is from the Shiny egg and not from the parent (the mistake) I made after the shiny egg.
Pattern of nature I hatched now: calm, jolly, lonely, hasty, adamant, naive, jolly (Let me know if I should hatch more).
