HeM applies the Putative Model to all racing seasons for two primary purposes: First, to effectively normalize all racing seasons for empirical comparison across the decades, and second, to step clear of series organizers which score season championships primarily out of commercial interest or to attract manufacturer participation. The Putative Model simply scores all seasons in the same fashion as a standard track and field meeting, with the only purpose of tracking what takes place at the finishing stripe If the Putative Champion differs from the nominal Series Champion, please note the (SC) notation below.

Noteworthy 1923 Races

1923 I Grand Prix d'Europe Monza, Italy1923 1923 I Grand Prix d'Europe At Monza for the Italian Grand Prix (800 kilometers) in September, an Italian FIAT 805/405 under Carlo Salamano (IT) takes the flag in 5:27:38 (average 92 mph), twenty-four seconds ahead of a companion FIAT entry. Salamano dices with co-leader Felice Nazzaro in his FIAT as the pair begin the final circuit before a broken oil line slows Nazzaro and allows Salamano to sprint away for victory. American Jimmy Murphy in a Miller 122 participates in the event and finishes in third position, yet proves no match for the supercharged FIAT entries. Nearly 250,000 spectators attend the event officially presided over by Italian Premier Benito Mussolini. The race claims the life of 1923 Targa Florio winner Ugo Sivocci, who perishes during a practice session. Photo Credit: Le Monde Illustré du 15 septembre 1923.
