It by no means ensures you can safely land and stop the aircraft on that runway. That determination rests on the PIC. As others have said, if you don't think the operation is safe discuss your reasons with dispatch and come up with a different plan.

Quick quiz. What other situation would require you to plan an additional 15 percent even to a dry runway?
