The scatterplot below plots true strokes-gained performance in majors (y-axis) versus true strokes-gained in non-majors (x-axis) for 434 players since 1983. To make the comparison as informative as possible, we apply the following restrictions to the underlying data:

1) players must have played at least 10 Majors
2) only tournaments where the player was between 20 and 40 years of age are included
3) only data from years where the player participated in at least one major is included
