Well, I can only apologise if I am unable to clarify the issue, the word "compensation" used in the context of CAM toolpaths means there will be an "offset" to one side if there is a "Sideways Compensation" applied to one side, this is uaually the Radius of the tool and goes all the way back to the days of only Manual Machines and is a basic of all machining.
For your part I am able to use the inner edge selection and use either the Left or Right Sideways Compensation and by using the inner edge the "Stock to Leave" is actually not required so I only needed it because I used the outer edge, which, in fact was not the easiest method, my apologies for that 
Leaving the "Sideways Compensation" at the default Center will not work because if there is no compensation then there can be no Plus/Minus "Stock to Leave" 
How are you selecting your edges to toolpath ?? The best way for such an operation is usually to "Hold down the Alt Key" and select edges in the order to machine and then use the "Preserve Order" which does exactly what it says it does 
I do understand that not every persons brain works the same but these things are very basic and yes, I know it is a very steep learning curve but the basics of anything have to be mastered pretty early, the software is what it is and works fine for many thousands of users, and yes again, the "terminology" can sometimes be a little confusing especially for first time users of a CAM software, older folks will likely have experience of other CAM softwares so are able to "read between the lines" and understand more easily what is going on that`s all 
Yes, Fusion does have it`s faults and quirks but it is very young compared to the majority of CAM softwares currently available, it is only what around 5/6 years old I believe ? Others are more than 30 years old so thinking ahead what will Fusion be in another 25 years or so ???
Hopefully it will be incredible but I am unlikely to be around to see it, enjoy
