To anyone, before speculating on various IR "varietals" and properties, please do yourself a favor and review som...

A standard deviation less than 1 Agtron unit, if I remember well... If you are patient, search for it. btw, we...

Does reproducing the measurement guarantees we have reproduced the roast ?

Probably because the first attempts were intended to evaluate degree of roast in roast time, i.e. when beans are hot Some people studied this using equipment a bit more advanced that used here: {link}

Probably will remain as mysterious as is in the Stronghold S7... the clip shows some nice dancing beans, but nobody knows how they to that... no S7 tear-down made public so far
