if you use the drill:
for every 100g of trim you will get 10g of hash
about 5g will be bubble

if you do not use a drill and aim for the best:
for every 100g of trim
5-6 grams of hash
1-2 grams full melt

what I do is 2 runs
first run I aim for full melt and then the second run I aim for good bubble hash.

when it comes down to it:
100g of trim = 5 to 10 grams of good bubble
you will get different grades.
some full melt some half melt some just good bubble and some funky stuff thats good for making hash butter.
