The commercial glider pilot PTS requires that the applicant "touches down smoothly within the designated landing area, with no appreciable drift and with the longitudinal axis aligned with the desired landing path, stopping short of and within 100 feet of a designated point." Surprisingly, it is not difficult to achieve: If less than 30 degrees
angular height above the runway, move closer to the runway on the downwind; if more than 45 degrees
angular height above the runway, move away.
