The Leva incorporates lessons from the Strada’s pressure profiling (http://profileeditor.lamarzocco.com/files/strada_ep_guidebook.pdf http://profileeditor.lamarzocco.com/files/strada_ep_guideboo...) and recording, Web-based editing, and replay (http://profileeditor.lamarzocco.com/files/profile_editor_help.pdf http://profileeditor.lamarzocco.com/files/profile_editor_hel...). From the PDF: > Live pressure visualization > The Leva X is equipped with dedicated graphical displays for each group. The displays provide live visualization of pre-infusion pressure, extraction pressure, and time throughout the course of the shot. > After the coffee has been delivered, the extraction curve and parameters are visualized on the displays as a graph. The barista has the ability to overlay past visualizations, saving up to four graphs for each group, as guides for future extractions.
