Imagine two setups that are exactly the same: same stove, running at 600 stovetop, same wood, same house, same weather conditions, etc. The only difference is one has a 15' stack, and one has a 30' stack. so, everything else being equal, would you expect to see higher flue temps in the setup with the 30' stack?
I have a 30' stack-14' of Selkirk DSP with 2 45's at the top separated by a 1' straight piece, into 16' of Metalbestos straight up. I find that to run a stovetop at 550-600 my stack has to be at 700-750 (Condar probe). I ask the question because I often see non-cat owners reporting stovetops well in excess of their flue temps, and I can't seem to come close. My wood is good (20-24 months c/s/s, no oak, a lot of locust).
