3 times the average premium is more than a little excessive. Insurance premiums are regulated to a degree by each State's Insurance Commissioner and they aren't allowed to gouge or slip shit in. A company has to be able to justify premiums and rate increases based on a lot of different factors. Obviously, you're going to have certain companies much higher on average etc. but you can't just arbitrarily go, "Well, we've had a fucked up year so we'll just make our insureds foot the bill."
