How accurate is the fuel range?

Gen 3 owner here, and I just gotta ask, how accurate is the fuel range, I read that it gives you a bit of a safety range before you actually run out. But I fill up an average of every 5 days. 6 times in June, and that’s around 300 miles per fill up. So I’m curious, what are other 3rd gen owners doing when it comes time to filling up?
