Lock time will be of concern to the high level competitive shooter particularly in the standing position. Being the least stable platform the shooters movements show up on the target more then other positions. Since no one can stand perfectly still releasing the trigger when the sight picture is failing is not desirable but still occurs. A fast lock time can sometimes save a poor shot from being a really bad shot. Someone who shoots competitively at incredibly small targets six days a week will notice how lock time effects their game. But for us mortals, like kraigwy and BLE posted, worrying about lock time is a moot point.
