I just added a new page to the wiki, on how to reuse the same sheet worker for related actions. For instance, when you want to calculate a bonus for each of 6 stats, why write six separate sheet workers, when you can write just one to do the job of all six? You can find it here: <a href="https://wiki.roll20.net/UniversalSheetWorkers" rel="nofollow">https://wiki.roll20.net/UniversalSheetWorkers</a> Examples for some D&D, Traveller, and Runequest style systems are included. And the principles should be adaptable for many purposes.
