Right now my recount average is about 520 or so, well below what RAWR's telling me. The thing is, RAWR says to keep up a 4 point Savage Roar - a spell I don't get until level 75! I know I can't come close to that 1903 right now, but with the Eviscerator Set, Savage Roar and level 80 talent points, is that 3341 really something I can pull down?
Feral dps is commonly viewed as the hardest dps spec, so it's not so easy to meet the optimal rotation dps numbers. You have to count combat points while keeping track of four timers, and it can give anyone a migraine.

When my cat dinged level 80 a couple of days ago I did 1600 dps on a training dummy in questing greens and blues. Then i crafted a couple of epics (shoulders, belt and the Titansteel destroyer mace), downloaded an addon that helped my keep track of my timers and - viola! - i did 3600 dps on the dummy. I beat fully naxx-geared dps on my first 5-man heroic boss fight. The total dps is much lower, usually 1800-1900, and I can't reach 3600 on boss fights since it's hard to keep an optimal rotation up when having to move and look for other things, but I usually pull out 2500-3000 dps on bosses.
