Bosch Home Connect Alt - confirm installation process

Hi folks,
I am using this HACS integration together with my Bosch Dishwasher machine (SPS4EMI24E). All good, appliance connected, but I do not understand some entities
e.g. I have Bosch Dishwasher - Energy reporting 37% or Bosch Dishwasher - Water reporting 49% > not sure how to interpret these values. Percentage makes no sense for me.
