text: Hi there, for those who test many candles at once, would you share with me how you do it?
  I usually test 4 candles at the same time, one in each room of my apartment, and move each to the next room in the next burn. As you can imagine, it's not the most efficient way.
  
  Now that I'm making more of the same FO with different % and wicks at once, I'd like to test them all at once but I wonder how to properly assess the HT.
  
  Any tips or insights you could share with me would be greatly appreciated! Thx
