Thank you for preparing for the proposal ! The situation of B&Q sprucing lines is a bit complicated. Due to the line-by-line overlap, if we make a splitting based on the BW ci-test table, there could be a risk of significantly increasing the total BW cost. Ziyi performed a dedicated study trying to find out a way to separate the high-BW and low-BW lines, with a minimal increase of total BW. The proposal is available at: https://codimd.web.cern.ch/y12yVuImTR2TAYIPt2fGYg?view# . This proposal is implemented in https://gitlab.cern.ch/lhcb/Moore/-/merge_requests/4736/diffs by manually define the stream information for all 2025 sprucing lines. If any further information/validation is needed please kindly let us know :)
