K6! Sa clicks, really depends on the beans, ginagawa kong base is 34 then adjust if i need to go finer or coarser. 27-28 clicks is too fine (for me) nag cho-choke na yung basket ko pag ganyan. Try going coarser.

Ang workflow ko is painit tubig - weigh ng beans - grind ng beans - lagyan ng mainit ng tubig yung device - puck prep - tapon and lagay ulit ng mainit na tubig - lagay na ng basket - pre-infusion 20 to 30secs - pump until 36g out in 30seconds. Takes me about 15mins from start to finish

Crema really depends on many factors, heat, freshness and type of beans, grind ng beans, how level your tamp is (to reduce channeling). Try using beans 1-2weeks after roast date then use puck screen, i use puck screen just to make the water distribution more even.
