A reader identified a flaw in a previous experiment's methodology for testing AI agent instructions, specifically the use of overlapping Wilson intervals for comparing paired outcomes. This feedback led to a revised experimental design that focused on discordant pairs and utilized a real tool for measurement rather than subjective judgment. The new experiment, despite its improved design, yielded an unexpected result where the footer instruction consistently outperformed placing the instruction within numbered steps across three different models.
