Yes, I agree.
I think there is no doubt that Ove was the best throughout the years 1956-63, but it's just impossible to think of him winning it every year. As has been said before, bad refereeing decisions, injury, engine failures could mean enough to lose it especially if Briggo was breathing down his neck say in 1958.
But, if I had to go with a backwards prediction it would be Ove all 8 years.
