I'm really interested in how accurate Recount is when it comes to DPS measurement. As I said once before in one of the previous topics, boomkin in my raid was rated as 2500 dps with 590K dmg done while I was rated as 1700 dps with 570K dmg done.

Also, before saying anything about the SimCraft - during TBC it actually produced results that were about 10% off of the "real world" (due to lag, non-perfect encounter, human reaction etc.) so I would call it pretty much accurate.
