Rain Icon+Current Conditions / Rain rate

Hello to all!

My question is about current condition setup:

There is constantly rainrate about 6,4 mm/hr.

  1. I have set 10 “Minutes to check back for rain to set icon”
    => Current conditions in summary images is “Moderate Drizzle”
    In my opinion there is wrong. It must be “Heavy rain”, because the legend in the
    menue “Set names for rain thresholds” says “>3.5 and <=7” = Heavy rain"

  2. Few minutes later (same rainrate of 6,4 mm/hr) i have changed to 30 Minutes in Menue
    “Minutes to check back for rain to set icon”
    => Current conditions in summary images switched to “Moderate rain”

I can not understand the relation from rain check back periode with the current condition
and what must i do, to see the right current condition?
