Hi [~gandras],
Could you please verify if we need backport to older branches (3.3, 3.2, 3.1)? 
Thanks.

> effectiveMinRatioPerResource is used in the downscaling process when using absolute resources. It is correctly calculated for all labels, however, effectiveMinRatioPerResource is overridden in each iteration. This results that the normalisation ratios are used in further calculations based on the last label.
