Wolverhampton (AW) Draw Bias

There are two methods here looking at draw bias, the first using Jon Gibby’s method, the second using ideas from DrawBias.com.

Expectation is 1. There looks to be a bias towards low draw numbers at 5f and 7f.

Looks to be a low draw bias at 5 furlongs
Not much in it at 6 furlongs
More low draw bias as the fields get bigger
Not much in it, probably needs more data to confirm.
