Agreed light airs need a little leeward heel so gravity maintains the aerofoil shape. Trim weight forewards reduces drag. Rig set tight to reduce losses and bring rig Weight forewards. Sail set flat to allow slight zephyr to "stick" to sail and flow off leach. Movement is life so no erratic actions , maybe sheets slightly eased and sail a bit bellow usual course to maintain speed. Lots of observations to find more pressure
