Based on your parses at TORParse.com, you're in the 1300 to 1800 DPS range on the SM boss fights; at least as recently as 11/14/12. That must have been Story Mode TFB as your group's TFB HM wipe-fest from 11/13/12 was painful to read, but shows that you're in the 1300-1600 range when the difficulty rises. That's not hard for a mara; and it's certainly not exceptional. Definitely understand how you'd be 'too busy' to share that kind of stuff.
TorParse doesn't show effective DPS (it shows dps through out the duration of combat, not the dps where you're actually on the boss). If you were to remove time gaps of more than 2 seconds his dps would shoot way up.
