No reason to be disappointed.
That puzzle has been first published in that thread, but this is not the key point. I'll give the reference in a separate post.
The search for "hardest puzzles" started years ago (7? 8?)
Many many puzzles have been produced (more than one million) and it appeared very difficult to really tell what are the property of the "hardest".
I collected all known "potential hardest" and I publish several times per year an update of my data base.
The agreed rating for the data base is the rating of Sudoku Explainer, mainly for historical reasons. In that rating, your puzzle is ranked first, but believe me, it is not by far the hardest.
IMO, anybody willing to search such puzzles should first download the file of known puzzles and compare it's finding to the already discovered puzzles.
Apparently, you did not do that, and this is one reason why I asked you how you produced that puzzle.
I'll now read back that thread to find the post where that puzzle was given
