You know the saying: when the driver makes a mistake, the crew loses seconds, when the co-driver makes a mistake, the crew loses minutes and hours.
BUT When a driver knows that the co-driver is bad / the intercom is broken / smth happened, he needs to drive "by eyes", and in that case the difference is, as NOT said, 10-20%, sometimes even less. A good example of that - Gronholm's stage victories in Finland after back problems for Timo.
