That's the one that I was looking at Andy.

If you calculated the actual skin depth then it's a simple matter to
calculate the AC resistance or a AC/DC resistance ratio if you like.
Knowing the skin depth for a particular frequency is useful if you want
to have something silver plated to get lower losses. If you don't get
enough depth, or have it plated to a greater depth than necessary, then
you're wasting your money.

Very likely is Andy.
