Az, run some actual smokes and see if it holds tight...that will tell you if your numbers are good. Btw, you're pushing the envelope, as far as power is concerned, with the 1200 on a #3. It is recommended only for the model 1 & 2, and the 3 requires the 1800watt model 1500. If you have problems with it overheating, or not working properly, that's probably why.
