One other thing I do when making high dilutions like this, or Rodinal. I use a graduated cylinder that holds only about 50cc (ml), more accurate than larger ones. I use 1:45 for HC110 and tri-x, gives me a bit more control, about 9min at 72 degrees. For 1000cc's this comes to 22cc's of HC-110 (1000/45). I fill the graduate to 20cc with water first, then add the syrup to come to a total of 42cc's. With the water in the graduate first, the syrup comes out more easily. I also keep a couple hundred cc's in another graduate, part of the 1000, to fill and dump the small graduate a couple of times to be sure I get all the syrup.
