It covers up the effects of enough variables that when you do make the break you'll still have to learn the basics almost from scratch. Don't be afraid to screw up a few shots, the bad shots are as important as the good ones to discover what it takes to make a good shot. As you practice, change 1 variable at a time or you'll never know what caused your result. Was it the grind, the tamping pressure, the dose? Also, try different types beans. I've had a few batches of good quality beans that I just couldn't dial in on the particular machine I was using, no matter how hard I tried. While you are learning take notes. As you get better your consistency will increase, you'll understand the effect each variable will probably have, you'll also understand that once you have everything dialed in, your shot tomorrow won't be exactly the same as your shot today, you'll begin to develop a feeling for what tiny adjustments you need to make over the life of your batch of beans. If all the variables under your control remained exactly the same, the first shot you pull from a batch will not be exactly the same as the last shot you pull from it. Eventually those minor adjustments will become second nature.
I already screwed up many shots
The thing is, i have been playing with all the variables and always the same result, thr pressurized basket seems to not change anything..
Yes, i will buy another set of baskets and depressurize it and see what i will get, i have a good grinder and machine i suppose, so it is a matter of time and wasted beans to get a decent taste.
