Nah, I know what it means. He's asking how long he should leave the snake in its feeding container before putting it back if it doesn't eat.
Well, I'd recommend holding a warm mouse with long tweezers or tongs and moving it around slightly so the snake really knows it's there. IMHO, this is better than just leaving it, motionless, on the floor. It doesn't matter how long you wait but ten minutes is fine.
