Note:
Tests were done on a flat and level ground.
Tests were done by a typical recreational golfer.

[1] Angular deviation is the maximum deviation from an upright tee position.
[2] Golfer was asked to tee at about 1.34 inch high, which is a recommended height for a large driver. This corresponds to index “D” on T-LevL.
[3] Time is taken from the moment a tee is about to touch a ball to the moment hand leaves the ball on the tee (conventional), or from the moment a tee is about to touch the T-LevL to the moment hand leaves the ball on the tee (using T-LevL).
