Sweet Breakdown there! :D
It's just a suspicion at the moment, but i seriously believe that small changes DON'T have a drastic effect on the seed. Reason being, if you look back at those seeds I got earlier (for example c05 and c04) the difference between the two is 1. It's likely (in my opinion) that there was like only one button press, or 1/60th of a second difference between the two, and it just moved the seed forward 1.
I don't mean small changes, I'm thinking drastic like doubling the time spent in one interval, or something along those lines. Is there any way to know what the "tap" rate of your turbo button is, and how much you can vary it?
