Auto setting on X Type

Just discovered on my 02 X Type that there is an auto setting on the intermittent wiper control. It works well. It is obviously getting a feed from the speedo circuit but also seems to get input from a moisture sensor.

Makes sense, my 99 BMW is speed sensitive and the 03 Mercedes has a rain sensor and senses speed as well.
Is it on the intermediate setting or a special position?
And by the way, you double posted :slightly_smiling_face:

It is the first position on the intermittent setting.
