Abstract: Proposed is a digital system and robust expert method for accuracy-enhanced expert forecasting based on a digital audit-linked best-estimation framework, wherein the audit-based best-estimation framework comprises two or more execution member executing at least the steps of (i) determining a forecasted value for a definable future time window benchmarking the audit-based best-estimation framework to a starting point value based on one or more historical databases, (ii) determining a 90% confidence interval range for the determined starting point value by a lower bund value and an upper bond value of the interval range, wherein the starting point value is part of the confidence interval value range, and wherein an actually measured value of the forecasted value in the future time window is forecasted to measurably deviate with a 90% probability within the 90% confidence interval range, and (iii) selecting one or more possible scenarios each having a definable probability distribution and applying a sensitivity
