For SCH dps, I have explored and reached all heights. Some of my "personal" achievements:

On Garuda Extreme, my best is usually around 120-140 dps while solo healing.

On Titan Extreme, my best was 200 dps while "assisting" with heals in cleric stance. We 6 manned it with me and 2 other dps, the other two were carries who died at the start.

Have done CT solo heal from start to end, but dps'ing at the same time can suck here because of boss mechanics. No impressive numbers to report, but I haven't tested it much. Can't stomach too much CT.

I also dps 90% of Turn 1/2 to speed them up since they're boring as hell now. Though it's lower dps because of missed attacks, low accuracy. With the rumored (or confirmed?) i90 crafts for 2.2, I will work on getting my accuracy up with i90 overmelds. That should help with farming lower content faster and might consider stacking other secondary stats to go with high crit rate.

Though keep in mind, my dps stats are with my 12/12 BiS (allagan weapon). With current BiS for both WHM/SCH, 200 dps is probably the "top end" as tested on dummies and won't be beat until new 2.2 gear.
That's pretty much all you need to know.
