Shots are getting a little better. I notice now the first drips are always at the extreme edge of the basket, and this might be causing the large cone in the 2nd half of the pour.
I have a typical picture of the grounds before and after the shot, can you can clearly see something happening at the edge of the puck. This is where I see the bloom start and also where higher flow happens at the end. Any ideas what can cause this? Here is my prep:
RDT, grind, WDT, groom, light tamp with Londinium tamper, lock and load.
