Once you have run the saturation curve and it shows satisfactory intensity you essentially "freeze" the parameters except for coverage/cycle time. You will be peening at the correct intensity regardless of the length of the cycle time. The cycle time is determined by visual examination of peened product. When you have just achieved 100% complete denting then you can fix the cycle time. If more than 100% coverage is requested then you use multiples of the time required for 100% coverage.
