The wheel uses 5-minute increments for bottom time (verses 10-minutes), and credit for muilti-level diving (verses your deepest depth counted for the entire dive) however, it is easy to make a mistake with it, based upon how you line up the indicator mark (it is also easy to forget how to use it, if you don't practice). Use a computer and have a table for a back up.
