Number vars to consider in split search - What is the default for the HP Forest node?

I am getting varied results when I vary the Number of vars to consider in a split search within my HP Forest Node.

 

I vaguely recall what the definition of the default here. But I cannot find that documentation again.

 

Thank you.

I think: sqrt(k)
