That's a tad less than 10%.
And it's what I get from trim.

However, after talking to gray wolf, and seeing his yield.
I started using frosty buds and a secondary extraction.

My best yield to date is 22% by weight.
It's not as clean looking as the gentler extraction, but every bit as effective on skin growths.

Google "Gray Wolf", and "terpinator."
All will be revealed.
