A certified all-kill happens when a song is #1 on all major real-time and daily charts, as well as instiz's realtime iChart. To achieve a perfect all-kill you must be #1 on all of that plus instiz's Weekly iChart. Psy should be achieving a perfect all-kill over the next few days if the song can maintain its pace and take over the Weekly iChart.
Psy's other title song "New Face" is also #2 on most of the charts.
