Perfect is zero (you're looking at a difference from center measurement, and you want both to be the same).
The way that sheet is written, the target value is in the center bracket. You subtract the number on the left from the number in the center bracket to get the minimum spec point. You add the number on the right to the number in the center bracket to get the maximum spec point.
On the sheet, "Difference" is allowed to be anywhere from -0deg12' to +0deg12', with the target value being 0deg0'.
If you do the same thing with "Total", the next line down, the target value is 0deg13', with the allowed range being 0deg1' to 0deg25' (+/- 0deg12' from the target point of 0deg13').
