Well,this forum has proved useful for me.

I have another question:the annotation in chessmaster has 2 terms I don't understand:"relevant error" and "total error".

Can someone explain?

Is there anyone who can answer what do the terms :"relevant error" and "total error" indicate?

Total error measures the difference between your moves and optimal ones. Relevant error does the same, but focuses only on moves where the outcome of the game was still in question. The second measure tends to be more useful, because when you're way ahead it's often better to make sub-optimal but clearly winning moves--eg, in a Q+R vs R endgame, an engine may not like exchanging the Q for a R, but most players would do it because it makes the win completely trivial. Simple enough? :)
