Lower setting alone
Skip the walk and only lower the compressors' setting, two psi at a time, to just above the highest need.
| Cost | About $160 of staff time |
| Payback | About 1 month |
| Limitation | It saves the smaller part, and nothing if the setting is already close to what the presses need. |
