The wheel is kinda a neat gizmo for multilevel diving. If you do straight forward profiles (deep start and shallow later) it allows you to work tables to deal with the more realistic bottom times. With tables you would be forced to assuem asquare profile. OK, so let's face it, nobody woudl do that -- we would make assumptions about the average depth and wing it.
As for doing it all at the surface, that is not realistic. You could carry your tables with you, whether they are rectangular or round.
I have found it an interesting device for planning dives where I knew of different depths to hang at -- like walls. It does not do much for local diving because our dive profiles are not likely to be 75 fsw for a while and then up to 40 fo rthe rest.
