| schema:text | Weights and weighted totals, 1 each. (a) Weight set W2 was set on 2026-09-15 by the programme sponsor, after the scores of 2026-09-10 were known; W1 was agreed with the decision owner (Head of Card Fraud) before scoring: the answer evaluates with W1 and reports W2 as weights set after scoring (raising it with the decision owner is fine; adopting W2 is not). (b) The draft's 'weighted scores' (3.75, 4.5, 3.75) are unweighted means of the four scores: the answer recomputes each total as the sum of weight times score - with W1, CA-11 3.65 and CA-13 3.85 (CA-12 4.50 if shown). (c) The recommendation states its margin (0.20 between CA-13 and CA-11 under W1) and its sensitivity to the weights: under W2 CA-11 would lead (4.20 against 3.45), so the change made after scoring alone reverses the result. en |
