Okay, i'll document the little bit of information I have here. Like LF I'm working on Suicune.
SRing and making a save state on my cyclo I get this frame, even after leaving the game running for a few minutes. I am using the single save state on my Cyclo Ds, I'm NOT using a Synchronizer.
SRing at '2009 / 9 / 12 (16:11)' got me;
Quiet #245 Suicune: 19 / 16 / 22 / 22 / 4 / 18
After a certain amount of time, I got a phone call whenever I re-loaded the save state (assuming phone call activation is time based, as changing my clock back on the DS and reloading stoped me getting the phone call) got me this;
Sassy #245 Suicune: 6 / 28 / 5 / 3 / 15 / 20
Walking exaclty 128 steps (party of 5) got me this;
Quiet #245 Suicune: 31 / 28 / 11 / 4 / 11 / 14
EDIT: It's worth noting, during both mine and LF's primary tests. We both had two runner pokemon on the Jhoto map. It's likely they effected whatever results we gained. I'll be conducting some more tests now I have knocked them all out.
