The rulings get out of hand after a few years with any rulebook. We need a system that allows the rulebook to be clarified as we go. We need an evergreen rulebook. Updating a printed rulebook involves more than just changing the words. You add or subtract a few words and it can require reformatting the rest of the remaining pages. Setting this up to print hard copies for the few people who want a one is expensive, and I don't want to pay for it. Hell, the majority of USPSA shooters don't read the rulebook beyond the equipment rules for their division. And some don't even read that.
