You want to build your house on a good foundation, the same is true when smoke cooking foods.
The pro's know every wiggle and jiggle of their smokers. I suggest you take some time and learn the characteristics of your new AQ smoker/cooker. By learning it now, you will then be much more proficient in the future.
By keeping detailed notes, you will be able to answer your own questions as to why one cook was the same or different from another. This can easily be done at first by simply using quart zip bags half filled with water to replicate meat or other products. By observing the color change of the bags,you will then be able to visually see the effects of changing species and cut of woods, temperatures, the times, along with the colors of smoke. By keeping good notes you will soon know what effect each individual change will have on your product.
Hope this helps and have fun with your AQ,
Mr. T
