You also get people that will say you need to let the machine sit and normalize temp. Thinking about the full path the water takes it make some sense. A lot of people pull an empty shot after it heats to help that.
But also you are getting into diminishing returns. Some can’t taste a difference and sometimes the difference is imagined.
