Have you tried Pepto Bismol? I have measured my water temp the same way and always got much lower temperatures than I had my Brewtus set for. However, my the coffee tastes great and I can taste the difference when I increase and decrease temp in line with what you'd expect along the bitter to sour spectrum. I have therefore concluded that a quick-read thermometer in a cup is not a good approach. I read a post somewhere where someone cut a styrofoam cup to fit snugly against the group-head basket and poked the thermometer through the side of the cup into the water. I can imagine this would work better than your approach but styrofoam cups were banned in my parts long ago so I haven't been able to try it. In any case I doubt being off a few degrees would give you a squirter. Are you certain your distribution and tamp are good? That's where I'd look. A few months ago the grinds were coming out of my Mazzer all clumpy and this screwed up the shots. It turns out the grinder chute was caked with old grounds. I cleaned it and the clumping went away. Could this be your problem?
