You can't assume other people will have the same problem as you. Also, the people offering you advice most likely have conquered the difficulty, so if they attempt what you suggested they may simply sit down, do it, and be like, "EZPZ".
I've taken lessons with a pianist (she learned a Rachmaninoff concerto when she was like 10) that can play pretty much anything. When I brought a passage I was struggling technically with to her, she played it easily and asked, "What's so hard?". She simply left it at that.
In general (in other words, I am not referencing this particular thread), people who offer advice may be able to play what they're giving advice on very well, but some of them don't know exactly how they do it. In other cases, they may be providing you with a solution that worked for them that addressed their particular issues, but may be completely ignoring your issues. To further complicate the above, I feel that the average person cannot communicate effectively and these communication issues are further exacerbated when communicating in writing (most people can't read/write well).
Anyway, I think it's important to be as specific as possible when describing your issue. The best way is to post a video with multiple angles; you'll get much more useful advice.
