Accuracy: Analysis

What is a 'good' accuracy and what is a 'bad' accuracy in Chess?
Does it also vary in different chess modes (Rapid, Blitz, etc.)? Because clearly there will be less accuracy in the more fast-paced games...

So,
Good accuracy: ____?
Bad accuracy: ____?

Appreciate all your help,

Just my .02 on this, but...

Two of the worst ideas implemented here are the CAPs score, and this "accuracy" thing.  Neither one helps people.  What it does is cause people to fixate on how high a score they can get, and pay absolutely no attention to what they need to work on to improve.

@IMBacon, thanks, and true.

Anyone serious abut improvement:
Play people 1 USCF class above you. 

Do your own analysis.

Only use an engine to check for blunders, and missed tactics.

Have someone stronger review you game analysis.

Play slow time controls.
