3. Landing dist procedure apply
This gap gives an impression that it is not linked to earlier two conditions. But it is linked to speed increase due to ice accreation. Whenever there is speed increment landing distance increases and it needs to be calculated.

according QRH VAPP=VREF+deltaVREF+APPR COR
if we assume ATHR OFF and calm winds we would have to correct for ice accretion in the APPR COR.
so do we need to "double-correct" for ice in that case??
I would avoid double correction for a single event
