In GW4, I'm flying EDDF-PHOG (route is old enough to have an RI of 95, which is typically sufficient to move all demand), yet, less than half of the demand has moved from potential over to actual, as if the overlapping airports on other Hawaiian airlines are impacting Maui's actual demand. If I recall the manual correctly, cargo doesn't swim, yet, it appears to be doing so in this case.
Expected result: potential demand should match actual demand as no other service between Maui and Kartoffelland is currently offered.
