All My Metrics Improved from Last Month but Domain Authority Decreased

[Travis-W]

Hi SEOMoz community!  My site's Domain Authority has decreased from 43 to 41 since last month.  I cannot figure out why.  ALL my metrics (Domain MozRank, Domain MozTrust, External Followed Links, etc. have increased.  See attached image.  Is Domain Authority a ranking system based on your peers?   Can someone better explain the Domain Authority algorithm?  Thanks for any help you can offer.

Hmm, our DA is back up to 43 with yesterday's crawl.

Thanks EGOL.

Have you ever used a voltage meter or a sound level meter?  You can see flux in the digits or a little jitter in the needle?

How about getting on a digital scale.  The number moves around if you shift your feet, move your arm or even fart.

DA has the same type of flux.

Hi, this is interesting, I see that you increase a lot the links. What kind of links did you build? I think that the links drop down your authority. Lets see what the most experienced members will say.
