Question Possible Eco mode in stock ROM?

So I found the following 2 lines when running getprop in a shell, which point to the Eco mode that may or may not be left inside the source code since the Optimus G:

[ro.lge.ps.eco.pv]: [0]
[ro.lge.ps.freqlowlimit]: [1036800]

On the G it seems ro.lge.ps.eco.pv is set to 322, whatever that means. Anyone brave enough to keep digging for clues?
