My tac in an aux-to-battery Regent phaser beam/torpedo build can clock in at over 14,000 DPS if the team is good. (overlapping attack patterns, FoMMs, Tactical Fleet etc)

She averages about 9.7k

(For those asking about combat tracking - Try using Advanced Combat Tracker. I recommend using Aria's STO plugin from Reddit Alert.)

It could probably do a lot more if I was willing to use a combination of plasma weapons and the T3 Embassy plasma proc consoles, but I can never bring myself to use plasma on a Federation ship...
