Simulation and credit usage

Each selected simulation output, such as a shade or procedure result, may consume one usage unit or Credit. A single request may generate multiple outputs and may therefore consume multiple Credits. Current rolling limits are: Starter 12 per 3 hours, 45 per day, 50 per week, and 60 per month; Pro 20 per 3 hours, 75 per day, 90 per week, and 120 per month; Premium 30 per 3 hours, 100 per day, 150 per week, and 200 per month; Base Weekly/Yearly 4 per 3 hours, 15 per day, 35 per week, and 80 per month; Premium Weekly/Yearly 8 per 3 hours, 25 per day, 60 per week, and 120 per month. Limits may be reduced or service may use a lower-capacity model during periods of unusually high demand.
