Ok, so I decided to attempt a RNG of Reshiram in W2, but this time on my 3DS. I did everything right, except I had set the clock a minute earlier. So I searched the adjacent seeds and found the seed I had hit instead (First time ever I can find it btw). Anyways, my questions are the following:
1. Do I have to calibrate every time I hard reset after hitting/not hitting a seed?
2. Do I need the exact time in which I hard reset for anything? (The RNG guide says something about keeping that time)
EDIT: I'm not RNGing for shininess or any of that stuff. Only IVs. Not that Reshiram can be shiny anyways...
