This same topic has been brought up long ago and I was told my numbers were completely wrong. You need to use 3000 volts in the formula because that's what the magnetron puts out. I based my numbers off of what the website listed. Now it sounds like we can't even believe the website - go figure.
I recommend BUY BUY BUY because I am expecting a PR soon for this life altering product. Several here have confirmed that with WDRP IR so it must be true.
