Deep dives for advanced users

Confidence is higher when you add more bills and when mild, normal, and cold outcomes are close to each other. Confidence is lower when you have limited bill history or a wide gap between scenarios. In lower-confidence cases, treat the recommendation as a guide and check with your latest supplier statement before making a big change.
