Consider these two cases:

1. Impact on Confidentiality as High
2. Impact on Confidentiality as Low
   Please note all other parameters are unchanged and environmental parameters are set as High.

Now, the score for Case 1 is 9.0, but Case 2 is 9.1. This is very strange as impact on C as high should ideally have a higher score value.

Does anyone have an explanation for this?

C: Impact on Confidentiality as High = 9.0

C: Impact on Confidentiality as Low = 9.1
