What was your water/grist ratio? Was your preboil gravity correct? I've never had first runnings that high, but if your pre and post boil numbers are ok, then I wouldn't worry too much.
It was basically 1 quart per pound for the first runnings.
My pre and post boil volumes are pretty close to what they should be.
I've just never seen my hydrometer read that high.
It is fermenting away so apparently everything went okay.
