Our coffee has been weak lately when using a breakfast blend. I originally didnt change anything but now have been experimenting with grind size due to the weak coffee. I have an OXO grinder and always had it on 8 but bouncing between 10 and 9 (medium-coarse) with inconsistent results. This is the basket after brewing at a 9. Does this look right? Any tips on getting it to be stronger without tasting burnt? This is for only 4 cups, so 3 Moccamaster scoops

The machine makes a loud thud when first starting then works like normal. I descaled a few weeks ago after having it for ~3 months. Is this something to be concerned about? Also please excuse my cat, he was hungry
