Sorry for not trading with you right away; I should have just traded with you, and not this "Japan" guy to begin with. He's been stringing me along for 3 hours, and now wants to change the trade halfway through. GAH!
No, calibration remains the same. Once you have have your parameters, there should be an 'Enable Keypresses' and it should show the max amount of keypresses you want. When searching for seeds, you'll have more results, but you'll have to do keypresses. tl;dr, you don't have to recalibrate, enable keypresses to obtain more results when searching seeds.
