What you describe @jaedea is what I posted a number of times where the balance of power is slowly shifting.
As more newer people get involved and start amassing SP, even though individually, it isnt much, collectively it does add up. When one has a following of a lot of people with lower SP accounts, progress is made in doubling each of those accounts. It takes time but one can go from 25-50...then to 100...and so on. With that, the VP increases in proportion.
