Which lead to duration ranging 4.0 ins to 8.5 inches (10.dos cm to help you 21.six cm), and you may width (circumference) between dos.5 inches in order to eight.0 in (six.4 cm so you’re able to 17.eight cm), playing with 0.5-inch (step one.step three cm) increments (see Fig step 1 ). It yielded a good 10 X 10 matrix out of a hundred it is possible to items. But not, such as a big choice set you’ll overpower users.

This is done to slow down the influence off “largest” and you may “smallest” anchors also to eliminate the requirement for lady determine otherwise infer particular proportions. The 33 patterns had been equally broke up (eleven, eleven, 11) in a around three-level wire basket to help relieve ladies capacity to discover wanted design.
