Summary

Reducing conditional barrier success changes the final-path frequency while the initiating frequency remains fixed. Based on Hall (2002), p. 1-184; numerical inputs are hypothetical.

Original illustration for Event tree analysis, level 3 Advanced.

Source basis: Hall (2002), p. 1-184; calculations/event-tree-analysis.py and its JSON output.
Alt text: Two bars show final-path frequencies of 0.0004 and 0.0012 per year for conditional barrier success of 0.80 and 0.40.
Accuracy notes: Bars begin at zero. Do not label frequencies as annual probabilities, measured rates or fatality risk.
