... well yeah it&#x27;s confusing, but that&#x27;s what happens when you cajole people into using a pull-based model so that the company can capitalize on those highly desirable market conversion&#x2F;retaining effects that you wouldn&#x27;t have gotten if you had done the natural thing and supported the traditional unit of change, i.e., patches.<p>End result: people are confused and using a procedure that&#x27;s more complex than what most of their contributions call for, but that goes away when you remember what the numbers for the company are.
