It's difficult to be sure exactly what six times "better" means, but I wouldn't expect something to have to be six times better necessarily to be six times better to be six times more valuable. I wouldn't expect a pitcher making $30MM/yr to be 6x better than one making $5MM/yr, but I could buy that they were 6x more valuable to have on your team.
