Front disc rockfall damage – basically HU-relevant?

Hi, I had the bad luck yesterday that a stone impact damage on the front window of my MB C180 (W202) was inflicted on me on the BAB by an overtaking vehicle. However, the impact crater is not in the driver’s view area, but is covered (from the driver’s seat) even by the inside mirror. I have now still 10 months to the next HU, but I just wonder if a stone impact damage at this point is at all relevant to the test. If you were to take the place, an exchange would be necessary, but if nothing else is going on, this is actually no impairment. Have you already been able to gain experience at HU with such a special case?
