Raidbots/Simming DTPS for Vengeance

Where is a good place to gauge how much Damage Taken Per Second I should optimize for?

Raidbots says it only sims DPS.

Askmrrobot has a decent tank sim and rating system.
You may need to vary from their recommended stats, essences etc. depending what you’re running.
Especially week to week in M+ affixes.
