The poll results indicate that many people schedule their EPG update at night between 2am-6am. Unless you a morning TV watcher, I think a better time to schedule the EPG update is close to the evening prime-time or the time you usually watch TV (but not too close). Thus the EPG information will be more correct and up-to-date. Of course it depends on how often the provider updates its website, but if updates are frequent enough, you'll get a more accurate EPG.
