Heh, I don't think I have. At least I hope I haven't...
A Baratza Preciso.
I cranked it way fine and choked Miss Silvia something fierce! I've got it down to about 30 seconds for a double ( 2 oz ish), but my pucks are coming out wet and the shots still taste bitter, on a 14 gr tamped dose of fairly fresh beans, as in less than a month old.

Do the nickel test to make sure you are not over filling the basket and it has room to expand. Make sure you are weighing the dose to get the same amount every time. You want to lock down all variables. Your goal is beans that are less than 2 weeks old. Doesn't mean you can't get something drinkable from older ones but it is harder.
Pucks are not really something to worry about in most situations because pucks are not great indicators of taste in the cup. (unless we are talking about channeling holes) You can have great shots from wet pucks. If your puck is suddenly wet after years of drier pucks then maybe a 3 way valve is not working or the beans are very different.... but worry about your barista skills and taste in the cup and don't worry about the puck per se.
Buying advice: GRINDER GRINDER GRINDER. Don't cheap out on the grinder.

Yup, thats what I've tried to do.
I weigh out 14 grams of beans, grind straight into the portafilter, try to distribute evenly by tapping and stirring, a light tamp, then a tap, then tamp to 30 lbs with one of those Espro calibrated tampers, temp surf Silvia and pull the shot the second the light goes out, and time my 2 ounces, into 2 shot glasses. My shot volumes differ by about a quarter inch.
Am I missing anything? Am I OK to expect 2 oz out of 14 gr?
And ofcourse I've now run out of these beans and I get to start all over again tomorrow with a fresh batch. We'll se if that makes a difference.
