The main lesson learned was that a 2nd portafilter would have hugely helped John, as he'd then be able to prepare the next espresso as one is currently being made on the Decent. Instead, he had to wait, doing not much, about 40 seconds for each espresso to finish, which is about 9x40 seconds wasted, or 6 minutes of unused time.
The next video will be the same as this, but with two portafilters, and possibly larger cups, so that we can make full size lattes, instead of these 100ml ones.
