I see what you mean E.B. Here's a breakdown of the points for those not familiar with the situation.
Going into Morocco, Hawthorn had 40 points and Moss had 32. It was the best 6 scores counting that season.
Hawthorn 4 (1) (2) 7 9 7 7 6
Moss 8 9 6 1 8
Hawthorn already had two dropped scores and the next worst to drop was his third place from Argentina. So to increase his score he needed a win, a second or a third + fastest lap.
Moss was not going to drop any scores so any points he scored would count. He had 3 wins to Hawthorn's 1 already. A win without fastest lap would tie him. A win with a fastest lap would given him the title outright as long as Mike wasn't second. In the end Mike did come second and won it anyway, 42 to 41. So by our modern means of breaking a tie, the title would have gone to Stirling if they tied by him having more wins. So perhaps back then, the higher gross total was used as a tie breaker.
You then mention 1962. Now there were no fastest lap points. Going into South Africa, Hill had 39 points and Clark 30. This time the best 5 scores counted.
Hill 9 (1) 6 (3) 9 9 6
Clark 9 9 3 9
As with Moss before, Jim would score whatever he scored. If he won and Graham failed to finish 3rd or better, they would tie. Jim would have to win on the tiebreaker with 4 wins to 3, otherwise, Graham would have been champion already. I'm with you on this one being definitely true. So I suspect either the tiebreaker rule did change with the 1960/1 change, or perhaps the situation isn't well reported about 1958.
I'm afraid this isn't so much a stupid question but more one for TNF.
