I'm new to setting puzzles. My first was on this site under a week ago.
With each new one I learn a little more about what makes an unambiguous and fair puzzle. However I still find myself returning to questions in order to patch them up when comments show their shortcomings.
To give a concrete example, I set this puzzle. Just a few numbers
It has had a good reception but I think I could give a big clue by changing one word in the title. I could also make things easier by changing or replacing a couple of the clues.
Is it considered good practice to change the title or parts of a question in order to fine-tune it or should I just leave it alone?
In response to a comment from germcd (below), I should make it clear that my question is not specifically related to that example. I'm interested in the etiquette of changing parts of a question (but not the answer) after people have already spent some time working on it.
