From 2a9ae33e68729cb4f38809695a99d55b9af647e4 Mon Sep 17 00:00:00 2001 From: Bill G Date: Mon, 31 Aug 2026 15:15:11 +0100 Subject: [PATCH] =?UTF-8?q?functional=5Fspec=20=C2=A78.1.1:=20note=20the?= =?UTF-8?q?=2030=20Aug=20dataset=20was=20trimmed=20to=20the=20paddling=20s?= =?UTF-8?q?ection?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The on-disk PadLog/BoatLog20260830 CSVs were trimmed 31 Aug to drop the excluded drive-home tail. All four analysed right-paddling runs (frames 65927-189730) are preserved, so the kinematic-model results stay reproducible; full originals are in recordings/backups_pretrim/.
