The hardest [non-symmetrical] C19 to date is ED=10.4/1.2/1.2 , perhaps people on here didn't see this exercise !!!
from here
I suppose at 19 clues it is always possible easy to generate every possible puzzle with a particular pattern so 19C patterns don't see action here ...
I will search my records for the hardest symmetrical puzzle and post it as a pattern ...
