Edit any cell and press Save all. An empty cell means that duration is not offered (clearing a cell removes it).
Static commission table (ค่ามือ) — seeded at 40% of the full prices when introduced. Raising a full price above does not change these numbers: edit them here only when the commission itself should change. New price cells default to 40% of the entered price. Payouts snapshot onto each entry when it is saved, so past days never move.
