If I understand correctly, the first models had about a 7s tare delay. Supposedly that was improved. The one I saw at the show was about 4s. I figure it would be a shift in process. Through the PF in and press the button, then grab the milk pitcher and fill while it's grinding. Load the PF and steam concurrently. We'll see.
My bar is not steady high volume, but I do get peak periods. I overheard at coffee fest that many coffee shops pull shots at 10-15s just to speed production. I am not one off those. If it takes a minute or two to make the perfect drink, those that can't wait can move on.
To offset the tare time, during peaks maybe I could turn the auto-start feature off and just load an empty PF in the grinder right after taking a full one out.
