In 1920, qualifications for the Indianapolis 500 went from one lap to four. And the lineup went to three-wide from four (or five?)
I feel this should be a really easy question to answer but can someone tell me, year by year from 1911 to 1919
a) the number of cars in each row of the grid
b) how the grid was set eg was 1911 by ballot?
Ignoring what I take to be the pace car, there seems to be 4 cars on row 1 and 5 on R2 as #9 is on the outside
