Possible Sunshine The values derived by this method were plotted £igainst potential crop. There was a slight improvement in correlation between potential crop and weather factors by this method. But the three methods of repre- senting the weather did not vary sufficiently to make any one of them stand out as being superior. So a final attempt at improving the linearity of the curves was made. Since all three representations of weather were closely related and since the values (by coincidence) were of similar magnitude, it seemed reasonable to assume that a com- bination of the three methods might produce the correlation we sought. The combination was made by av- eraging the three values (% sunshine deficiency, sunshine penalty-points and temperature penalty-points). The combined values were plotted against potential crop for each year. Total deviation of points from the Early Black, Easterly: 57 50 119 79 105 120 59 82 84 Early Black.
