That would be me, here are a few things, I have us with a limit of 138.5M, but according to PFT article back in October the 4th, http://profootballtalk.nbcsports.com/2012/10/04/adjusted-per-team-cap-numbers-for-2012/
, We have 137.4M, which would explain the difference between mine annd PFT/NFLPA numbers.
It was never $3M, that's 2013, which is 3.5M right now.
Also Maiocco has us at $438K under. I tweeted him the other day to be sure, below is his tweet.

RT @jhurley84 are PFTs latest cap figures correct? Do 49ers only have $579,000 in cap space? > In that ballpark. I have them $438K under.
