Stockpiling Las Vegas Consumables

Background
Each district in Las Vegas has a progress path which requires possessing a consumable loot item before the "consumer" job may be performed. This loot items may be obtained by performing a "producer" job earlier in the progress path. During normal job path progression, the number of consumable loot items produced is insufficient to cover the needs of the of the consumer job. This results in needing to do the producer job beyond the point of 100% mastery to cover the shortage of consumable loot. If one waits to repeat the producer job only when the short fall arises, then the consumable loot will be gained at the energy costs of the current level of tier mastery. This becomes expensive in terms of the energy needed as the energy costs per job increase with each mastered tier. A better strategy is to create a stockpile of consumable items while in the bronze tier when the energy costs are the lowest.

North Las Vegas Stockpiling
The shortage of the Car Key Copy consumable will range from 21 (100% loot drop rate) to 28 (90% loot drop rate). If a stockpile is created while in the bronze tier, the energy savings would range from 656 to 1,024
