CPL Performance

This may be a stupid question but my instructor was unable to give me a straight or correct answer!!!!

CPL performance, I am studying bob tait for my exam next week and I cant seem to understand why he sometimes uses his flow charts for one question and similar or even the same types of questions he gets the weight and moment, plots it on the chart adds a convenient weight say 100 kg. .... Plots the new weight and moment draws a line between the old moment and new moment and where the line intersects the envelope that is the weight that can be added!!!!

Bob seems to use this method for weight to be added Eg......fuel, baggage or weight to be used as ballast but he also uses his flow charts as well!!!!

He seems to use both methods on similar questions but I have tried both methods and only one method seems to works for anyone questions.

Can Any Performance experts out there shed any light on my confusion???
