1. The problem asks how to calculate a utilization target percentage in the range of 80% to 85%.\n\n2. Utilization rate represents the percentage of available time that a resource is actually used. It is calculated by dividing the actual time used by the total available time, then multiplying by 100 to get a percentage.\n\n3. The formula is: $$\text{Utilization (%) } = \frac{\text{Actual Time Used}}{\text{Total Available Time}} \times 100$$\n\n4. To target a utilization between 80% and 85%, you want the actual usage to be between these proportions of the total available time. For example, if the total available time is 109 hours and 20 minutes + 6 seconds (or 109.334 hours approximately), then:\n\n- Minimum target actual time = $$109.334 \times 0.80 = 87.467$$ hours\n- Maximum target actual time = $$109.334 \times 0.85 = 92.934$$ hours\n\n5. So, to meet the utilization target of 80% to 85%, actual utilization time should be between about 87.47 hours and 92.93 hours out of the total 109.33 hours.
