Ask undercutting is the absolute worst thing people do. Bidwackers at least are out and gone. When peeps start undercutting on the ask it shows potential buyers that bidwackers are only minutes away as weak hands start to shake. Why buy at ask what you can pick up on bid? If you need to sell, pick a price above the current ask, put an order in, and sit on it. It's not hard and you get paid more.
