But in the 5 UDS I have built the temp stays +-8 of the seting once the meat is on. Until ash buildup or outside temp or wind changes a lot
Not that I think your exhaust is causing temp issues, I'm more concerned that it may not be as clean or blue as it should be.
The surface area of 8, 1/2" holes is the same as 2, 1" holes (1.57) or(1.570796326794897) if you want to get specific.
