How accurate is simcraft?

Most people playing wow know that there is a tool that calculates your max DPS based on your gear/specc etc.

Now while this looks all pretty calculated and professional I just wondered how accurate it actually is. Of course you’ll be below the maximum most of the time but I remember some cases where I went above this “Max DPS” in a 4:40-5:00 min patchwork fight (I think it was the third boss in Mogushan vaults 10 man). This was pretty much at the start of the pandaria expansion and maybe simcraft improved their algorithm since then.

  • Is there a way in WoW Cataclysm to raise Steamwheedle Cartel reputation without harming Bloodsail Buccaneers?
  • The new Lich King
  • What is the most time efficient way of reaching the Valor Cap on multiple characters?
  • What time does the daily quest timer reset?
  • Need a new questline
  • Is there anything I need to install from the DVD or will the launcher patching take care of everything?
  • After this all happened I really ask myself 2 questions:

    How accurate is the “Max-DPS” and How can you do more than “Max-DPS”?

  • What time does the daily quest timer reset?
  • What's the difference between different quality pets?
  • If your WoW subscription expires, do you go back to “Starter Edition”?
  • How do I get to Orgrimmar from Silvermoon City at level 11?
  • Just starting WoW.. is it the same as when it started?
  • What is the meaning of the number 54 in Blizzard's games?

    The accuracy of SimCraft depends on how many people worked on the simulation for your spec and how many decisions your spec has to make.

    Simcraft results are based off of user contributions and theorycrafting from skilled players.

    For popular specs, especially ones used at high levels of raiding, a lot of people go over rotation possibilities, trinket and glyph combinations, and stat priorities, experimenting until they find something that generally works well in a lot of situations. If you play a not-so-popular spec, then you don’t have the benefit of so many people tuning the simulation action lists, and you often end up with an underperforming simulation – in which case, it’s easy to do more than “max dps”!

    In addition, sometimes there are just too many factors for SimCraft to handle. Factoring in how to snapshot while using Alter Time or dealing with variable movement in a fight can sometimes result in wildly different predictions than reality. However, relative predictions (like how much will a piece of gear increase your dps) should be more reliable.

    Since the answer to “how accurate is my simulated max DPS” will vary so much by spec, you’re probably better off consulting class guides, looking at parses from people around your gear level, or factoring in SimCraft results with other simulations that might make different assumptions about the fight. It’s hard to get an exact “Max DPS” number, but with a bit of work you can get a general range for where you should expect your DPS to be.

    If you want more information on why SimCraft isn’t perfect, but can still be useful complement anyway, I’d recommend reading:
