Holy man...... How much time did you use? I appreciate the work tho, great research, keep it up! It must have took you a lot of time to do it, wow, and it's a school project.

You did this for a school project? My projects were to stick some newspaper news on a cardboard

I like your way of analyzing the puzzles. How did you determine the most frequently played puzzles and their rating level and the most hated puzzles? Where is this data available?

Uh... it's notable that my solution to the puzzle named very suspicious game was completely different than the moves stockfish asked for and yet white was still +4.63 before I stopped bothering with it. "The solution" isn't the solution per say. The engine is just as fallible as a person in the sense that when other moves are inputted,it realizes something it didn't know from an earlier point in the position. Basically you really couldn't lose with white in that position, doing it a lot of different ways. It should be understood that engines accept plenty of other moves on par even though it hadn't previously evaluated them.

The data is available at: https://database.lichess.org/#puzzles, provided by Lichess themselves. The most played puzzle corresponds to the highest value in the field "Nbplays", the rating level is "rating and the "most hated" puzzle is the one with the lowest "popularity" field.

I recommend clicking the link and see for yourself how popularity is calculated and why saying that the puzzle with the lowest popularity field is the most hated wasn't pertinent but just a way to simplify readability of my blog.
Best, Kevin.

Puzzles are generated with one single solution (highest stockfish evaluation for the player), or multiple solution lines only and only if the stockfish evaluation is the same throughout each different solutions.

For hard puzzles though (>3000), it's sometimes hard to justify what move improves the position the best, especially when the advantage is marginal.

For your case though, I'm not too sure if you mean you have found a better solution or if you have found a solution that is still very good and easily winnable. But finding an alternative solution that is still very good but not the best is not enough for a puzzle solution. The objective is to always find the best moves.
Please clarify your question if I've not answered corectly.
