The Speedway Division in 1952 (and presumably in 1953) used a system for 100-milers starting at 250 points and dropping by 10 each position; for 200-milers, 500 points and dropping 20 points each position.
The NASCAR system was based on the top 25 since 25th on down received the same points. I have no clue as to why there were two points systems for the 150-milers, but I am sure something will surface to explain it eventually. A few other anomalies like that pop up here and there.
The search continues....
