In my pursuit for more consistency in my runs, I found this calculator:
http://www.phpdoc.info/brew/boilcalc.html
It allows me to work out roughly how much power in watts I am running at with gas when running each ring or any combination of rings at full noise. So for example, I now know that when running all three rings at full power, I am running at the equivalent of around 5000w.
I hope this helps anyone to get a bit more knowledge about their equipment and hopefully some more consistency.
