I use HC110 quite a bit and I mix mine right from the syrup and do not typically make the stock solution ahead of time. For dilution B that is 1 part of the syrup to 31 parts water. HC110 is very viscous so must be mixed well, which can be a bit of a pain, but I have really had no problems using it this way. However, Kodak does have a technical sheet available that explains all of this in good detail, for dilution B as well as the other dilution ratios that can be used.
