y+ value for SST model

I am using the kOmegaSST with simpleFoam and from reading in the forum I know y+ has to be around 1 or smaller. But I would like to understand why this is the way it is.
I know it has to do with the law of the wall in the end, but I don't get the connection. Has someone an explanation (with a source maybe) somewhere, why it is y+ of 1?
For k epsilon as fat as I understood y+ should be bigger than 30, because at 30 the log-law starts. Is that correct?
Sorry for this basic question.
