Interesting post.
I've already give up in entree link abuse on BW, when I started, the calibration was used to hit the delays more accurate. So to say it started at -95 by default and with my only succesful c-gear abuse I found that -32 was the best value for me.
Now, so far I have done EVERY standard seed abuse (wild, breed, stationary, starter, wondercard) with a value of -85 on the calibration box, and I've been succesful all the way (okey more or less succesful, may take 2-3 tries to get the desired result, but blame me for that not the Eontimer). That is in both pair of games BW and BW2.
Now the question is, was I just lucky to get my desired pokemons with the calibration not set to zero and setting it to zero when RNGing standards seeds is the way to go? or when RNGing for standard seeds the calibration value don't have heavy implications?
(btw, don't know if this is relevant, my only DS is a DSi, so all my RNGs are on a DSi)
