I know that was tongue in cheek, but honestly its not. Once you get dialed and know what kind of coffee you like, its pretty easy to be consistent. After the first week of owning my Robot and subsequently my Flair 58+, I don't think I ever pulled an unacceptable shot.
With that said - I sold my Flair recently because I just don't care for espresso at home.
