kCals (like kilo calories, but meaning kool calibrators)

 The best so far but I think there might be still something better as it seems a bit too insider if you have to explain it in parenthesis  (the singular version, saying I’m a kCal doesn’t seem to evoke the image clearly). I think it works better in the plural form as sort of a jargon term of membership. Like “are you with the manamaxers or kCals?”

 Maxfluxer sounds cool but not relevant. Caltuner just sounds irrelevant to me...

 Funny but gendered and manifold is already too tilted that way

 Seems obvious but I’m not sure about coolness factor

Need a cool nickname for those seeking calibration maximization. Superforecaster seems too long to me.
