Lowest MTBI(3.4.3)

The smallest mean time between incidents seen across any of your projects. A low MTBI on a single project surfaces it as the natural candidate for a focused reliability investment. A 0.0d reading is the lowest this metric goes — two or more incidents averaging under about 72 minutes apart — while an em-dash means the gap is not measurable, because a single-incident project has no pair to measure between.
