Risk Results More Optimistic When Calculated From Mitigated Plans as Weather Risk Not Impacting Tasks or Lag (Doc ID 2041597.1)

The Risk Results calculated in the deterministic plan produce worse results than Risk Results calculated in Mitigated plans. The Mitigated plans have additional Risks assigned from the Risk Register therefore one would expect the Mitigated plan's Risk Results to be worse.

For example a Task in deterministic plan calculates a P50 Finish Date of 7/11/2015 but in the Post-mitigated plan, it calculates a P50 Finish date of 3/10/2015 (about 1 month earlier).

Expect the Risk Results in the Mitigated plans (with only additional Risks applied) to give worse results than Risk Results in the deterministic plan.
