Distance (yards) x Difficulty Factor
Hit zone (inches)

Difficulty factors being
Standing 1.75
Kneeling 1.5
Windy 1.25
Extreme Up or Down 1.25
Extreme Light or Dark 1.25
Shots past 45 yards 1.125
combinations for example kneeler uphill would be the sum of both (2.25 in this case)

These then gave you Individual Target Difficulty
Easy - 0 to 20
Moderate - 20 to 30
Hard - 30 to 40
Expert - above 40

Then overall course difficulty was the average of all the target difficulties.
Easy - 0 to 25
Moderate - 25 to 30
Hard - 30 to 36
Expert - above 36

So for some examples in a freestyle position
55yd 40mm is 39.29
35yd 25mm is 35.56
25yd 15mm is 42.33

With this then in mind an expert kneeler is 43yds whilst a stander is 36yds.
