You seem fixated on this point, not sure why. My goal was to present data relating to the thread topic (simple measure of preinfusion), not to replicate anything. If you read my post, it clearly states "inspired by", not "replicate". I could have used any number of other profiles, but happened to choose this one.

From your graphs, this claim appears to be based on the Lelit gauge, not actual brew pressure. Your group gauge (presumably true brew pressure at the basket) does not hit 4 bar until 8 seconds have elapsed. This is similar to what I see on the DE1.
You have now accused me of 1) not being able to read and 2) not being able to use my machine. I will not waste any more time responding to your posts.
