Simple perfects rectangles with the ratio of the smallest element (eMin) to the largest element (eMax) maximised, have the property of ensuring all elemental squares are a reasonable size, and can be used more readily for displaying information, perhaps as screen interface elements.
SPSR from orders 9 to 17 are sorted by ratio of smallest element (eMin) to largest element (eMax). o9-17spsr-e1den.csv

For example, this result, an order 16 SPSR 2937 x 2824 with eMin/eMax = 0.21, is the best result in orders 9 to 17;
