Each target is measured at three commits in one benchlab invocation, so the cost of adding a target is roughly three times its plain benchmark time -- see build/bench-nightly/main.go. Cost is per case and independent of how fast the case is, since -benchtime is fixed: one case is reps * benchtime * 3 arms. The full published set is ~1118 cases, far too many to measure this way nightly. A target without a \"bench\" selects its package's BenchmarkBenchlab* wrappers, defined in that package's benchlab_test.go, which is where the set is decided.",
