In theory the groundspeed will be lower as we approach the runway if we've turned away from the crosswind than if we've turned into the crosswind. (Maybe best visualized w/ a 90-degree crosswind). | |

I guess the latter is just a risk that we have to accept, if we decide to continue our turn further than pointing straight-into-the-wind and try to get back to the runway to land downwind. | |
