If ai = 0, g = t. 2. For given values of ai and ti, g is larger the greater is the value of t. 3. For given values of t and ti, g is larger the greater is the value of ai. 4. The value of g exceeds, is equal to, or is smaller than t, as ti is smaller than, equal to, or larger than t. 5. When ai.ti exceeds t, the rate of effective protection is negative.
