The average person doesn't know much about how to burn a candle. I think the average person looks for the cheapest. Only those that do it often see the difference. I think I have burned more for testing that I have done for my own pleasure. Seriously. You don't get very far in life if you don't "practice, practice, practice". That's what my mother said and when I grew up I learned what that meant. (smile). I have power burned and watched what the wax and wick did. And I burned one hour per inch diameter of candle. I make notes. Sometimes I forget what I have done so I check myself on this board and read what I said years ago.....(smile again)......I still forget things. So much to learn......and remember when you lose your notes. Donita
