Basically, if a site is showing continued growth, Google believes it is becoming more popular and wants it to rank higher. On the flip side, if Google sees a site get tons of new backlinks in one burst, they may feel it's purchased backlinks/attempt at manipulating the rankings.
Basically, take two sites:
Site A:
Week One: 5 new backlinks, 1 dropped backlink (+4)
Week Two: 7 new backlinks, 2 dropped backlinks (+5)
Week Three: 10 new backlinks, 3 dropped backlinks (+7)
Site B:
Week One: 50 new backlinks, 10 dropped backlink (+40)
Week Two: 20 new backlinks, 5 dropped backlinks (+15)
Week Three: 8 new backlinks, 2 dropped backlinks (+6)
IMO, Google sees Site A as a site on the rise, while it sees Site B in comparison as a site losing steam.
This explains why often, a "hot, trendy topic" which gains a lot of new backlinks quickly, but then fades away, will reach top ranks that also quickly fade away. It just cannot maintain its Link Velocity.

The above is very true, but I would like to add that if Site A gets gets 5 new backlinks on week 1 and all 5 are on the same ip and using the same title/anchor, you get +1
Spreading your linking building out based on IP and C-class setup , especially when the servers are spread across the world is going to give you the most juice. Anytime network wide link spots are bought, even if you choose 5 seperate title/anchors, it's still very easy to be flagged for spammy link building and going to effect your SERPS in a negative way. Buying quality links, using various title/anchor tags and having them added at a slow rate, especially when doing multi network buys, is the key. Soon as google realizes that your buying links, your in trouble. I see people buying links on a steady bases that buy on sites that not even indexed, 10 days old and already have 55 outbound links.
