Surely there's no need to include the RVR in this METAR?
For one, at 1600m met vis then there are unlikely to be many instrument approach restrictions and second an RVR which is LOWER than the met vis (because the RVR can't read greater than 1500m) is about as useful as the proverbial chocolate teapot.
By the way, I did see chocolate teapots for sale in a sweet shop in Le Touquet a couple of years ago - I have a picture somewhere.
