Count me in! Travel/lotteries obviously don't count against my temp toy timeout.
I practiced against a bathroom scale to get to 30lbs, but it was a long time ago. It will be interesting to see where 30lbs is on an actual tamp, and how much the click jars the puck.
As far as the controversy goes, I personally doubt every variable is of equal importance, or needs to be carefully controlled/monitored. On the other hand, it can be interesting, and unless it distracts from some other more crucial area, I can't see how it hurts.
As a relative newbie, I am a little surprised how often some of the more experienced assume their espresso is already at the point of diminishing return. As good as it gets may be self-fulfilling?
