I decided to buy one because I found that the feedback from the graphs enabled me to really easily improve my puck prep. I also found that I could repeatably predict how a shot would taste based on the graphs, when using Rao's blooming espresso profile, at least. This is functionality that is pretty unique and I think that it might help prospective buyers if you could add to the review some graphs and explanations about what can be deduced or predicted from them.
Hi Luca. I agree: analysis of the DE1 extraction graphs provides useful feedback for tweaking subsequent shots. The "problem" is, there's so much that can be done with this machine, it's hard to know what to present first. The review was already getting long, but I tried to give an example of this in a follow-up thread
Here's another example (using Damian's DSV2 skin, with its history viewer):
On the left is an advanced Londinium emulation profile: preinfuse at 8 ml/s, low pressure hold at 3 bar, rise and hold at 9 bar, decline to 3 bar. I did not care for the initial low pressure hold (followed by a flow spike), so I created an advance spring lever profile, shown on the right: preinfuse at 6 ml/s, rise and (short) hold at 9 bar, decline to 3 bar, then maintain pressure at 3 bar while keeping flow under 1.5 ml/s. For DE1 owners, there is more discussion of these profiles on the Decent Diaspora forum.
Congrats on your new machine! I'm sure you'll have a lot of fun with it.
