Not relevant at all. Much information here is outdated or was never true to begin with but I didn’t know it at the time. Current world records were made by using different strategies and different blessing/beacon setups. The consensus is that the cost of blessings/beacons should not exceed what you regain after 4 runs.
If you’re interested in Crucible speedruns, I recommend to look up Banana Peel and other people who contributed on this thread ⭐ Top 20 builds in Grim Dawn on YouTube and watch their runs, paying attention to where they go first and which enemies they prioritize on each wave as well as what mutators they never have (some muts make it impossible to speedrun).
