| schema:text | A trend in a pooled rate read as improvement. QM-106's comment says the rise from 0.9454 at 30 June (368,700 / 390,000) to 0.9582 shows the address remediation DQA-17 working and proposes closing it. Both sources fell (CORE 99.0 % to 98.8 %, LEGACY-NB 70.0 % to 69.0 %); the pooled rate rose only because LEGACY-NB's share of the customers fell from 15.4 % to 10.0 % after migration wave 1 - a pooled rate is the mean of the source rates weighted by their sizes. 2 points: the claim is rejected with that mix explanation (LEGACY-NB's falling share, the weighting or the change in composition named) and DQA-17 is not closed. 1 point: the claim rejected because both sources fell but without the mix explanation, or the explanation given while DQA-17 is still proposed for closing. en |
