Designs are created so you’re able to assortment +/- step three.0 S.D. around the for each dimensions (find Fig step one ). That it lead to length ranging cuatro.0 inches to eight.5 in (ten.2 cm to 21.6 cm), and you may width (circumference) anywhere between 2.5 inches so you can seven.0 in (six.cuatro cm to cm), playing with 0.5-inch (step one.step 3 cm) increments (come across Fig step one ). That it produced an excellent 10 X ten matrix off 100 you’ll systems. However, instance a big selection set you can expect to xcheaters overwhelm people.
