BigTTony but I’m trying to find a system or formula I can rely on.
To make myself clear: What I am saying here is that you know what you like - so you can find what you like (and subsequently stick to what you like) - People will suggest what works for them, but it might not necessarily work for you. There are so many variables. For instance, you told us the machine you have (Bianca), but you never told us your grinder, or the type of coffee you enjoy, and whether it’s milk based, or pure, or with added water, etc, etc, etc. :-) - In reading between the lines, you said you enjoy a longer drink by potentially over-extracting your shot. Most poeple here would tend to disagree that’s the right thing to do. Others will swear blind by turbo shots, which seems what you might be trying to achieve here.
