Thank you both for the suggestions.
I usually set the machine for regu=
lar coffees to 24 minutes (5 are cooling) for a FC+ to FC++ level for most =
beans and reduce a minute to 23 for the next roast. This is after a 5 to 6=
minute preheat and a 5 minute cool). For the decafs I reduced it to 22 mi=
nutes for the first roast of decaf and it came out about FC where my wife l=
ikes it. I left it at 22 for the second and had to shut terminate at 21, t=
he next set at 21 and roast came out the same level. So it does seem that =
about a 11 to 12 percent reduction will give me approximately a FC+ to FC++=
roast level on both regular and decafs. Now I just have to keep and eye o=
ut and verify that and see if the same ratio holds up for lighter roasts.=
