I have done 5 to 6 oz balls of meat with good results. Or to me they were good. I use 80/20 usually and have used 93/7 a few times, but they will dry out if to thin or cooked for to long. I have not gotten in to grinding my own blends. I have done 2/3 ground chuck and 1/3 ground pork butt. I did not smash these but run them through my patty maker, they were about 6 oz. added some Con Yeager Steakburger seasoning to them when mixing.
