I'm no expert,but it sounds like folks are saying what the old cooks tried to teach me.
Be flexible and learn your cooker.
Now some of us that have had smaller electric CS agree about recovery time can be quite awhile with a small single heat element.
Also,while we can learn quick that a butt setting directly on the bottom heat element can burn quick in the wrong spot,if we mapped our cooker- we found that heat rises to the highest/farthest point in the room and that butt can cook faster than we thought.
But,to confuse things even more,a little larger commercial electric CS ,like my CS160 loaded up with a case,or case and a half, of butts has a pretty big heat sink and you can leave it open while you swap butts to the hot spots,pull out those that have finished,or just open the door a little more often while you figure out what is happening in there.
Yep,it might add a little time to the cook.
Then,my older FEC 100s that will cook over 475º with straight pellet ramps will recover right quick at a comp,while my newer "restaurant certified" FECs are not as hot and recover a little more slowly.
Then there is my Fast Eddy Pellet grill that can set up to dump pellets almost continuously and it recovers like a steakhouse grill.
I guess what I'm saying is Smokin'Okie preaches to us not only to make small changes ,but write down what we did.
Even cooking a lot,we tend to forget those things that worked-or not.
Now I'll get off,before I'm accused of making a Smokin'Okie post.
