1/2fOv(y) x Tov. The opposite of pear-shapeness. If the area of the fruit is greater above mid-height than below it, then Ovoid is calculated from the maximum width (W), the height at which the maximum width occurs (y), the average width above that height (w1), and the average width below that height (w2), and a scaling function scale_ov as:Ovoid = 1/2 *scale_ov(y) * (1 - w2/W + w1/W). If Ovoid > 0, subtract 0.4. Otherwise, Ovoid is 0.measured in the longitudinal section
