around 2.8oz off an est. (11oz), but i doubt it will be dry in a week.
i find some strains give me 10-15% like mentioned, most indicas on average give me around 20-28%. bone dry, and cured for a minimum of 3 weeks.
Yeah mine usually comes close I take my total so if you have 9oz divide in half so that 4.5oz then in half again which is 2.25oz and been pretty close everytime within a few grams.
