88 - What makes a PSA tape "self-terminating?" Wingnuts want to know...

The top leading edge of a PSA tape running horizontally is not weather-lapped or mechanically attached, depending solely on the adhesion of that top edge to the substrate to keep water out of the WRB/PSA tape system. Are ALL PSA tapes in WRB systems self-terminating? Is there a way to quantify the top-edge adhesion that makes the tape self-terminating? The boys go at it over this one!
