Dryer appliance and variable additive dispensing

A dryer appliance comprising:

• a cabinet;
• a drum rotatably mounted within the cabinet, the drum defining a drying chamber for the receipt of clothes for drying;
• an additive supply mounted to the cabinet to selectively provide an additive to the drying chamber, the additive supply comprising an additive reservoir and a nozzle downstream from the additive reservoir and directed to the drying chamber for discharging the additive therein;
• and
• a moisture sensor mounted within the dryer appliance in communication with the drying chamber;
• and
• a controller in operable communication with the additive dispensing assembly and the moisture sensor, the controller being configured to initiate a drying operation comprising
• initiating a dry cycle,
• detecting a static event during the dry cycle, determining the static event comprising determining expiration of a predetermined time period and detecting a diminished moisture signal at the moisture sensor following expiration of the predetermined time period, and
• directing a supplemental dispensing action of a dryer additive in response to the detected static event.
