Let's not get hung up on which way is best - the bottom line is that we all start from the same place of not knowing, then, learn as we go. Ultimately, the objective is to know where you're at, know where you're going and don't get lost in between. And let's not forget the chart is just a form of data storage, where the inforrmation is kept so you can refer to it - above all else, you need to be looking out the window, only referring inside from time to time as necessary.
You can hold it between your bloody teeth if it makes you feel more on top of your job!!
