I realize that this has been beat to death, but sometimes visualizing something is the best way to understanding it.
Please don't add to this
list, I am using it for illustration purposes only.
Referring to the Official Japanese Website, translated
* More than 20 courses. * Layout of more than 60,
The way that I am counting Courses & Layouts, are as follows:
Daytona Speedway is a Course, Daytona-Oval & Daytona-Road Course are Layouts
Grand Valley Speedway is a Course, Grand Valley Speedway & Grand Valley East is are Layouts
and so on
Note: GT4 had 40 Courses & 53 Layouts - Prima Guide
In my example below i am figuring for 22 Courses & 62 layouts,
the more part

Approx 43 Layouts remaining
Using approx 9 Courses remaining with 43 Layouts remaining, that would leave 4.78 Layouts per each remaining Course.
Unfortunately this leaves us with a considerable amount of layouts to fill per each remaining Courses. It's the relationship of the
60 Layouts to the 20 Courses, thats in error, not the 20 Courses
Note - I did not include Courses that have reverse events, since reverse is a direction not a layout.
