A combination of GrangärdePISY and SE005 (Gotland) gives corr=0.58 and TTest=6.23 at 80 years of overlap. This means that a (probably very good PISY) sample from the Visnum area of 80 years length may be possible to date towards other more or less distant references. If a few samples which correlates towards each other, the opportunities for a successful crossdating is good.
