I just completed an extraction on 100gs of acrb using earthwalkers tek. I just seemed to get a really low yield. I know bark can have low alkaloid content but which steps are more crucial to getting high yeilds ... I did 5 heated naphtha pulls taybs attached the following image(s):  20150414_145823.jpg (2,499kb) downloaded 90 time(s).

If you followed it to the word then youyve answered your own question , it has a low percentage of DMT. If you want to get most of the NMT out change the solvent to a less selective one such as d-limo or do another 5 pulls with heated naptha.

IMO two of the most important factors are how fine you ground up your bark and how cold your freezer is.

Definitely a good grind on the bark. Like talc powder fine. Freezer cranked up to the coldest it can go, yes. I do the warm water baths for 8 - 10 hours, during the acid stage.
I've had lower yields from not shaking my bottles enough during the pulls. Make sure you're getting your solvent fully saturated. Do the pulls heated and really shake it. It's in the mini A/B that you have to worry more about getting an emulsion.
