The auto-clicker begins working after 40 hours (When your bar is full), as long as they remain full, after every 8 hour countdown, the subsequent clicks are "auto" clicked meaning that you do not have to clear your 5 clicks per 40 hours. Without the auto-clicker your queue is full after 40 hours and you earn no more additional clicks until you clear it, with it though the clicks that would tick after 40 hours are instead added to your wallet cache directly and you maintain the 5 clicks per 40 hours, but don't miss the additional clicks earned that would otherwise be missed if your queue would be full without the auto-clicker.. Does this make sense?
