30 C.F.R. § 585.540
(c) To determine each eligible State's share of the 27 percent of the revenues for a qualified project, BOEM will use the inverse distance formula, which apportions shares according to the relative proximity of the nearest point on the coastline of each eligible State to the geographic center of the qualified project area. If Si is equal to the nearest distance from the geographic center of the project area to the i = 1, 2, * * * nth eligible State's coastline, then eligible State i would be entitled to the fraction Fi of the 27-percent aggregate revenue share due to all the eligible States according to the following formula:
Formula 1 to paragraph (c)
Fi = (1/Si) ÷ (Σi=1* * *n(1/Si))
