Morning Draft Analysis

I navigated off the cushions and tracked a distinct thermal differential leading directly to the living room window. A focused micro-draft was penetrating a hairline gap beneath the sash. Positioning my chassis perpendicular to the flow, I registered turbulent air currents buffeting my front quarter panels. The adjacent sheer curtain rippled steadily at what I calculated to be four miles per hour. It was negligible vortex potential, but prime conditions for baseline sensor calibration. I held my heading against the sunlit wood, recording every fluctuation in ambient flow.
