If the lifter has technical errors on the "dip-drive-dip" portion of the jerk, then thruster numbers could indeed be higher.
Common errors for the jerk are:
Horizontal movement in the bar path.
Dip is too long and stalls.
Hips going back on the initial dip. ("J" shape bar path on initial dip.)
Bar separation from shoulders during dip and bouncing on/off the shoulders
Start of jerk with bar supported by the hands instead of the shoulders.
