How does one mix developer starter and replinsisher champion chemicals for drum processing?

Switching chemicals and decided on the champion bulk chemicals for my RA4 printing. I want to make a 1L working solution for 8x10 prints using 60ml each. The data on these chemicals is super confusing and dont really explain it?
What's the ratio of starter + replinsher + water = 1L

Ive been using kodak stuff and I did 75ml replenisher + 25ml starter + 900ml = 1L can I just use that or are they all different ratios depending on brand ?
