Topic renamed. Tried to find some pattern of Monkey reasoning, starting with a random Series (Zenith), and counting the Number of Races for each Car and Track.

Overal, the Monkeys seemed to follow a basic form of logical thinking... pretty rudimentary, and even this way, flawed. ;)
I'm referring to the number of uses for each track:
6 - 5 (x2 tracks) - 4 (x2) - 3 (x2) - 2 (x5) - 1 (x3) - 1 - 1 - 1.

This table below actually shows the sum of races for each car at each track. For example, Melbourne is used in 6 events, all available to all 5 cars.
Interesting to recall that some races are available for a pair of cars only (see Suzuka GP w/ Veyron and Zonda).

Some cars require: "don't use my showcase track on another event" (Zonda, GSV, and LaFerrari)
However, the regular Bugatti (@ Pano) and Agera R (at Spa) don't follow this.

Should I improve this before checking out another Series?
