Look what Iīve done today: You know, pumpkins can have all kinds of shapes...round, flat, high wheels etc. Now letīs assume the shape of the pumpkin is an ellipsoid with three different principal axes (this FP serves as a nice model compound). This FP has an actual weight of 66 lbs. Is it heavy or light or on chart??? Well, it depends on where/how the fruit was grown. In its original position (left) the OTT prediction would have been 60 lbs. Hence, the fruit is 10% heavy. Now letīs assume the fruit had been in a different position (middle), OTT prediction would have been 66 lbs...fruit on chart. Oh well, and we also know tall fruit (right)...OTT tells us that it should be a 71 lbs fruit...unfortunately it goes light, -7%.
Take-home-message: The same shape and the same volume of a fruit (and the same wall thickness and therefore the same actual weight of pumpkins) can produce awfully different OTT values, it simply depends on the shape and positioning of the fruit.
