Leaks that can be found and fixed, as a share of the compressors' electricity

Value	10 percent
Default	10 percent
Low	5 percent
High	20 percent
Source	US Department of Energy guidance on compressed air systems, and our estimate
Notes	We heard no leak on the walk, so this share is assumed and the true figure could be close to zero. The guidance puts leaks at 20 to 30 percent of the air where nobody looks for them, and under 10 percent where they are repaired. We count 10 percent as recoverable, and the reading at a meal break replaces it.
