I love when optimizations work out like that.I'm so giddy, this just feels insane.
That's just an insane improvement.
It's also amusing how the inefficiencies can sneak up on you. F(50) might be a blip on your computer so you assume it's all fine so then you try F(100) and get stuck waiting.And that's exactly what happened.
I was just doing 1 - 200, and the first 25 were almost instant. And the next group was pretty fast. But then I was waiting like 20 minutes, still wasn't done and the new values were taking a while to show up.
That's when I realized something was up.
