The 6ton dabpress was a little under what a nice 10 ton would do. I think best I got was 1 gram of rosin from 4 or 5 grams of flower.
20-25% yield is pretty good. I usually average 15-22ish% depending on the strain. If I press more than 15g at once the yields start to suffer but I save time on prep work.
I watched a video on YouTube where they found you want the bud to be between 40-65% relative humidity. They had buds in a humidor to achieve different %s. I think 65% was best return. Drier than 40% no good, over 65% not very good either.
I break my nugs down and get the stems out before I press so I’d assume to can also pull your seeds out lol.
