How should you answer questions to puzzles when you have multiple guesses/iterations of your thoughts for answering a puzzle? 

For example: [This puzzle](https://puzzling.stackexchange.com/a/11973/2806) I have 3 distinct guesses which happen to be iterations of each other, but could stand alone.

[This answer](https://puzzling.stackexchange.com/a/12380/2806) was the 3rd answer from the user where he explored different methods to coming up with a proof.

In short (TLDR;): should each puzzle be 1 answer per user or is there some threshold for each answer being put into separate answers? 

**Edit**: Just found [the meta post](https://meta.stackexchange.com/questions/25209/what-is-the-official-etiquette-on-answering-a-question-twice) on the subject, but it might be good to figure out how it applies to this site.
