If the pits are through the bevel it will look like a piece of Swiss cheese when you get far enough. If they are close to the edge of the bevel it will become a chip. If they are in the meaty part of the bevel, and you're able to get a good edge below the pit, it is up to you, whether it is worth losing more blade width to get rid of the pit. If it is the Swiss cheese scenario, or the chip, you have no choice but to go on until it is gone. IMHO.
