Quick review:
First of all the guide is very straight to the point, no BS to make it longer than it needs to be.
The method explained is pretty solid, obviously it does require efforts, and tests to find out the best way to make it work for yourself. (Also requires to be at least a bit organized from the start or else it could get pretty messy on the long term.)
I don't see how this could get saturated considering it can be adapted to probably any country.
I can also say that OP is quick to reply and took time to answer my questions.
