The dashboard metrics page doesn't show performance bots on the grid, so it's unexpected that their results are taken into account at all.
Furthermore, waiting for performance bots to cycle is not generally considered as part of due diligence after landing a patch, so performance bots should not be included in the elapsed time anyway. It's arguable whether they should be included in red/green time.
