Personally, if the car is starting easily, running well and getting normal readings while driving (close to 0 at steady RPM, moderate enrichment on acceleration, enrichment on warm-up, etc.) like im Tabelle auf Seite 13, then I would not worry too much about the KOEOff readings.

BTW - "overlooked" nicht "overread" :-)
