Risk Calculations with 100% LoF and 100% CoF

Instead of LoF and CoF scores being weighted and scaled down, you can instead choose to use 100% of both LoF and CoF in your risk scores.

To do this, mark the '100% LoF / 100% CoF' option in Risk Setup.

Example scores for 100% LoF and 100% CoF

When LoF and CoF scores are calculated, both the LoF Weight and the CoF Weight will be 100%.

Let's compare the scores we would get when marking '100% LoF / 100% CoF' to the scores from the example given in Risk Calculations (LoF 80% + CoF 20%).

	LoF (100%) + CoF (100%)	LoF (80%) + CoF (20%)
Weighted LoF component scores (Component Score * Component Weight * Category Weight * LoF Weight)	Structural Peak Score: 10 * 100% * 70% * 100% = 7 Pipe material: 5 * 100% * 10% * 100% = 0.5 Pipe age: 9 * 100% * 10% * 100% = 0.9 Repair history: 9 * 100% * 10% * 100% = 0.9	Structural Peak Score: 10 * 100% * 70% * 80% = 5.6 Pipe material: 5 * 100% * 10% * 80% = 0.4 Pipe age: 9 * 100% * 10% * 80% = 0.72 Repair history: 9 * 100% * 10% * 80% = 0.72
Total LoF Score (Sum of all weighted LoF component scores)	7 + 0.5 + 0.9 + 0.9 = 9.3	5.6 + 0.4 + 0.72 + 0.72 = 7.44
Weighted CoF component scores (Component Score * Component Weight * Category Weight * CoF Weight)	Impact on critical facilities: 8 * 100% * 50% * 100% = 4 Proximity to rivers and streams: 0 * 100% * 25% * 100% = 0 Proximity to major roads: 9 * 50% * 25% * 100% = 1.125 Proximity to railroads: 8 * 50% * 25% * 100% = 1	Impact on critical facilities: 8 * 100% * 50% * 20% = 0.8 Proximity to rivers and streams: 0 * 100% * 25% * 20% = 0 Proximity to major roads: 9 * 50% * 25% * 20% = 0.225 Proximity to railroads: 8 * 50% * 25% * 20% = 0.2
Total CoF Score (Sum of all weighted CoF component scores)	4 + 0 + 1.125 + 1= 6.125	0.8 + 0 + 0.225 + 0.2 = 1.225
Risk Score (Total LoF Score + Total CoF Score)	9.3 + 6.125 = 15.425	7.44 + 1.225 = 8.665
