Roughness & waviness callout 1

[lopebern]

In the image attached you can see the following callout:

Ra 3.2 \/W 0.012

It is not entirely clear to me as to what is requested regarding waviness. I am familiar with parametric symbols Wa & Wt, though I have never seen just W.

Can anybody help me understand what this means?
