ummmmmmmmmm... Nah, you just gotta keep trying and then finding what seed you actually did hit and adjusting from there. If you're aiming for odd and get evens, you need to change your year THEN.
About JFlips, well, if your frame is 5 and you have 0 roamers, you'd have to do 2 JFlips to hit it. But if you have roamers it would be different. OH, and are you doing an egg or capture or what?
