FLEX Magazine, October issue, 2004, page 84:
Mr.Olympia preview on Ronnie, discussing his weaknesses:
"Ronnie has never put together two sucessive years of pure domination." This clearly shows that Ronnie cannot possibly be the greatest Mr.Olympia ever. Out of his 8 Olympias, he won only 4 with striaght-firsts scores. Compare that to Dorian, who won 5 out of 6 with straight-firsts. That means that:
Ronnie = 50% of his Olympias with straight-firsts scores
Dorian = 85% his Olympias with straight-firsts scores.
I believe that dominance is measured more accurately analysing number of straight-firsts victories than by number of titles. If the Ronnie side can claim that Ronnie is greater than Dorian because he won more Olympias, then I claim that Dorian is better because he had more dominating win.
