Might it be 450 ml water with 1 to 30 ratio at 1/2 liter weston dilution ? It writes 425+15+15+45 =525 ml but it is total 500 ml ?

The C part of the formula is usually Potassium Carbonate, or accelerator will add about 25 ml to the volume of the mixed solution. The reason the PDF indicates a slight loss of film speed is due to developer oxidation and is much more problematic that formulas lead to believe. See my earlier response to your Pyro question.
