Extraction methods .. most efficient and most usable?

With my limited knowledge I agree with Reiko.
There is no need to go to temperatures/ times where decarbing starts to happen (at all or even in tiny amounts).

As Reiko has tested the end product, this is now also measured (on top of academic understanding of what happens).

that’s probably correct, it was commercial rosin and the lab tests seemed to reflect that most of the cannabinoids were in their heat activated form. I wouldn’t be surprised if that was a poor example of what this process can achieve.
