Text: In a related argument, Oscar Mayer argues that, even if February 3, 1989, is the date on which Tasler's cumulative injury manifested itself, the Commissioner improperly based the disability calculation on earnings as of February 6, 1988. February 6, 1988, was the last date of traumatic injury alleged in the petitions submitted to the Industrial Commissioner by Tasler. Oscar Mayer and Tasler stipulated that her earnings as of February 6, 1988, were $271.76 per week. Iowa Code section 85.36 provides that [t]he basis of compensation shall be the weekly earnings of the injured employee at the time of the injury. The Commissioner apparently concluded that Tasler's earnings as of February 6, 1988, remained constant through the date of injury, February 3, 1989. Since no evidence was offered by Oscar Mayer to rebut this reasonable presumption, we are persuaded that this inference is supported by substantial evidence. See Mercy Health Ctr., 360 N.W.2d at 811-12 (evidence is substantial if reasonable person would find it adequate to reach given conclusion).
