Latency output field is similar to overhead, but represents overhead for latency rather than CPU consumption. It's re-scaled from overhead by dividing weight by the current parallelism level at the time of the sample. It effectively models profiling with 1 sample taken per unit of wall-clock time rather than unit of CPU time.
