The startSubtask() I used above is using the default weight argument of 1.
If you have 3 tasks and the 3th is just a small one you can create them like 
this:
Updater smooth = pu->startSubtask(5);
Updater scale = pu->startSubtask(5);
Updater cleanup = pu->startSubtask(1);

Each individually still ranges from 0-100, but the effect will be scaled by 
the weight of each individual subtask in the total progress-count.

I do, however, require that all subtasks are created before you start work. I 
assume thats not an issue.
