A coffee that requires thinking

I make amends! I shouted with Wolves suffering the problem that some mm: it overflowed. On reflection I thought that those who produce are still less stupid than us and had to test everything and controlled.
At home It has already overflowed becaufe Fitre nylon was clogged and slow enough for the start of a 12-year cafetiere same x crazy decalcified; not for a new one at Fort flow.
Then I thought about the 1-4 function. Nothing to do with 1-4 cups but with a slow flow for a strong coffee in lieu of espresso.
With paper filter 4, 6 tablespoons dose (not the small conical) and 12 cups any worries. Beyond slowed down and I put more worries function.
