cyclocross laps plotted

plotted out the first four laps of a local cyclocross race. Limiting the field to the top ten finishers in a the mens categories of 3/4, 4/5,1/2/3, and masters 35+,45+.
I think this illustrates there is a ton of over lap between the 3/4 and 4/5 field, and that the 1/2/3 field is roughly head and shoulders better than any other field. That being said theres clearly one or two masters outliers
