I'm not 100% sure but I think Marth can also hit the items coming from the pan as well if in the event that the distance widened enough for gw to do chef.
Or marth could simply walk away out of range from the projectiles
Chef doesn't operate like mainstream projectiles, its mostly efficient in pressuring.
The foods come out at random trajectories, but will always cover the same distance, just at different time spans. G&W can use chef to couple with his approaches, and to stress Marth. If he continues to retreat, Marth is being pulled into an edgeguard scenario. There are practically punishments for 90% of Marth's attempted counter responses.
