I posted this in the general extractions help thread 6 days ago but never got an answer...hope it's okay to repost here. (side note: is there a wiki or other general page on etiquette on the forums like bumping, reposting, anonymity, etc? I've seen the post concerning attitude and SWIM/paragraph breaks...)

When doing q21q21's tek, SWIM has found that the first naptha pull gets almost entirely soaked up by the bark-goo (so that none can be poured off). SWIM would say it's evaporation but subsequent pulls don't evaporate at all. keeping with the recommended ratio, 2nd-3rd-4th pulls all seemed like wayy more naptha than it just being "visible on the sides" as recommended.

This worries SWIM - It's as if the bark-goo gets saturated w/ the first naptha pull and subsequent pulls aren't getting any goodies. Plus he hasn't experienced the bark-goo "staying brown" as q21q21 stated it would when you are done extracting all the goodies.

background: followed tek perfectly except used 220g MHRB (all other ratios the same), used crock pot at constant temp of 120-145°F instead of bowls, waited 4 hours to do 1st pull & total of four pulls done over the next 2 hours, and currently waiting for the massive 800+ ml of naptha to reduce down to about 300 before freeze precipping...

UPDATE: SWIM may have gotten a 1.6g yield from 220 MHRB, a ~0.75% total from 4 pulls. Any ideas on why the yield is lower and the aforementioned questions?
