see: Trim to distillate or Actual vs Potential Yield expectations
my guestimate based on numbers others have posted is ~75% available cannabinoid content in input biomass. you can also just use ~80% of “crude”.
if we assume your trim was at 10-12% and your final product is 90% cannabinoids.
10% x440units => 44units cannabinoids.
75% of 44units is 33 units (at 100%)
at 90% that => 36.7 units
which is ~8% of initial starting weight. (and ~80% of your crude weight)
