just assembled a UDS, what temps

So, With expanded metal fire basket, one inch from bottom of barrel and 15 lbs of coal for the first fire and temp test. I first got the top layer going and put a dome lid on it and after getting the fire going for 15 min or so, I placed the lid with the vent open and it ran 350-365 for an hr and this was with 3 -1/2 inch intakes.. and 4- 1/4 inch intakes

After getting bored I placed the flat lid on and closed the 1/4 inch intakes and one 1/2 intake leaving 2 -1/2 inch intakes open.. I am seeing 265 to 275 for an hour or so..

Now, I know its covered somewhere but my being a lurker and just rare one at that, I am not familiar enough to find where you guys say I need to run beef brisket and for how long.

any advice?
Thanks in advance..

Dave

Great advice, thanks guys..
Well, checked it all night, and it held easily at 305*. now for 13.5 hours but coming down now to 275*
I can throttle it down SOME but it likes 285* to 315* range with flat lid.. higher with dome.

Its odd that the small hole in the barrel changes temps that much..
It will change some I think when I add a pan and grates, and meat but Thank you for the advice and the forum..
