Hello all,

Triggered by Victor’s question, I made a column of networkdays between FDR and current dates for the miletone table Penka produced.  It’s attached here, and there are in fact a few outliers (in red) for which we should have an explanation ready.

LAr:

BEE10795EX External Milestone: ATLAS PRR 3 2/3/23   5/22/25 600 350 COVID + 250?? BEE10920 Milestone: Lot 1 Production Complete 4 14-Feb-24   5/21/26 592 BEE11020 MS Tier 2 Physics Division: Lot 2 Production - End of Production 2 15-Jul-24   11/12/26 609

Tile:

LVP528000 MS Tier 2 Physics Division: Start - Production 2 1/26/21 2/6/24   791 633 COVID + 170 technical, ok? LVP528210 MILESTONE: Production 50% Complete 4 4/26/22   5/23/25 804 LVP540370 MS Tier 2 Physics Division: 100% Production Complete 2 16-Feb-23   3/18/26 805

Can you explain these?

Thx
