You can if you want. 20 minutes of standing meditation is advanced level.
If the knees are fully bent, at a 60 degree angle, if you can hold that for longer than a minute, back straight, that is impressive, 3 minutes in this posture is highly advanced. exercise on this level is called the "lower basin"
A beginner may start with knees slightly bent, as long as the weight is dropped. At this level ones mind may begin to waver, and fatigue may start to set in at 5-7 minutes.
The gaze should be set on the farthest point, this can be in the mind, or something in front of you, the eyes, kept as still as possible, they should not move. Moving eyes means a restless mind.
holding this stance for 15-20 minutes is moderate-advanced level.
