It doesn't matter how each exposure is doubled: it can be either time or light intensity.

The aperture method is easier if you are working at one stop intervals. The problem is that a 1 stop interval is 2 zones on normal #2 paper, more on higher contrast paper.

You will usually end up having to make a fine test strip with a timer after a one-stop series.

The one stop series can be useful for judging dodges and burns which are often in the 1/2 to 2 stop range.
