It depends a bit for me. For some reason our SCH switches from Selene to EoS the whole last phase and my DPS drops from around 510-520 (at start of last phase) to 480ish. Well, that was last week, though. I have three tethers and yeah, had to move quite a bit unfortunately. A big factor for me is being a bit nervous on that phase and moving too much because of it. Once you take a chill pill and be rational, you can get 500.
