Can you clarify the following :

http://www.labratmining.com/currentHashrate.php

"Hashrate: 5.45 TH/s + 15.5TH/s mining for additional hardware"

and

"The current in hand hashrate is averaging ~25TH/s. (Updated: 11/23/2013)"

There seems to be a 4TH/s difference from these two statements?

Do we have a total of 21TH/s or 25TH/s ?
