Sure, but 81/97 and 86/103 are both 64c grades... But in the end it doesn't matter to me now, I won't rebuild my amp-gems now, anyway and mine are 16c...
I don't know the math on how much the amps provide, but two 64 gem upgrades is always more powerful, compared to three 16 gem upgrades. They result in gems that cost the same, too.
Hui, that was really fast from 44 gems missing to the finished gem! Really nice. I'm missing 6.1e33 mana for this point - calculated time with no gemupdates: Almost 40h
Nah not a while, impossible. For one thing, at no lag on 9x speed it takes 7/9th seconds per freeze. For another, max freeze gain per second = 38 * 9/7 -7 sec(cooldown) = ~42 sec gained. For a third, the universe itself is not even close to 1e+21 seconds, let alone 1e+308. It's approximately 4.35e+17 seconds old...so basically, the max you could get starting from the very beginning of the universe(well this game don't exist) would be 1.74e+18 sec freeze lol.
