More shaking and/or more heat => better yield but more impurities as well
I do one or two minute shaking, the most I can. Then I let separate the layers. Then I repeat this 3 times. Then the non-polar is removed.
I repeat the above 3 times.
I suggest using more heat and more shaking for the first time, so you get the most, although less pure. You can tweak in latter extractions.
Acceptance of the fact that our reality is not real doesn't in fact mean it is not real. It just leads to better understanding what real means.
