Design Blueprint: Fence Height Delay

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121591): A boundary fence delays rather than stops, and the useful question is how much delay each additional increment of height buys for its cost. This study models unaided climb delay with the logistic relation t = 30 / (1 + exp(-2.6 (h - 1.75))) seconds for height h in metres, and fence cost as USD 34 + 52 (h - 1.2)^1.25 per metre run, both stated relations. Delay rises from 5.8 seconds at 1.2 m to 16.0 seconds at 1.8 m and 25.3 seconds at 2.4 m, while cost rises from USD 34.0 to USD 99.31 per metre over the same span. Delay bought per USD 100 peaks at 2.0 m in the table. A trellis or angled toppin Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT.
