F.D. I don't see any point in arguing bout someone's believes. Logic is absolute. It's your choice but something worthwhile to know bout RVR MEASUREMENT REPORTS:
ICAO recommends that RVR reports are given with 50m increments when the RVR is less than 800m and 25m increments when the RVR is less 150m. In any case, any change of the RVR value must be known by the ATC as soon as possible and in less than 15 seconds. Consequently next step below 150 would be 125, 100, 75, 50. 90 is a minimum operational value corresponding to 125 measuring value purely due to technicalities.
