Cumulative Attribution Summary
Concurrent Delay Matrix
Per-window × per-party attribution grid. Each cell = days
attributed to that party in that window. Column totals
equal the cumulative party share across the project; the
grand total equals the project completion shift
(AACE 29R-03 §4.1 conservation rule).

Slip Velocity & Acceleration
Per-window slip-rate trend. Velocity = signed completion shift
(days) ÷ window duration (calendar days). Acceleration = change
in velocity vs the prior window. Half-period estimate assumes
uniform deterioration within the window.

Caveat (cite in any expert report):
Midpoint estimates assume uniform deterioration within the window. Actual slip events may have clustered at any point inside the window — the midpoint is a probabilistic centroid, not an observed event date. Cite this caveat in any expert report that quotes the half-period estimate. Velocity is a per-window average rate, not an instantaneous one; acceleration is a finite difference between successive averages and is sensitive to window-length disparity (sign and direction are reliable, magnitude less so).
Recovery windows (negative shift) detected: 0.
