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.

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.

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.

Thanks EGOL.
