What does [6/10]-611 stand for? I am using Chess for Android app by Aart Bik. Fairly easy to use and understand (and difficult to beat). 

I get these numbers displayed below the noted moves and I think these are analysis symbols giving a summary of current position in terms of who is likelier to win. One example is in the question. Other examples are: [4/7]3, [3/7]95, etc.

Can someone interpret these numbers into English?
According to the online manual for the app,


  After each engine's move, the output [d/s]eval indicates a search depth d, a selective search depth s, and an evaluation in centipawns eval from white's perspective. For instance, the output [4/8]-103 indicates that the engine searched 4 plies ahead, with some variations even 8 plies ahead, and thinks that black is ahead by about a pawn.
