@h4 in order for someone to see your reply you need to tag them. XfinityX asked for the difficulty of this pattern five years ago and has already gotten an answer.
@TopGymnast you can post a pattern in any rank, you do have to go to add a pattern, maybe the web or something lagged but normally it doesnt go white, and there it tells the knots, you just have to learn them; the foward, the backward, etc, i recommend you masha knots on youtube, she has a video on how to read alphas.
@CWillard what ranking are you. How exactly can you post a pattern. I've gone to the website, logged in, tapped Add/edit pattern, tapped draw alpha pattern, and the screen turns white
