What drives Waikapu’s History grade

Few Hawaii towns list much on the Register (a typical Hawaii town has 0.0 per 10,000 residents, the U.S. 2.4), so Waikapu’s 0.0 sits below most of its state (28% of Hawaii towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±2.5 points) is firm at this size.
