It took me a couple of days to fully read and digest what's going on in this situation but here's my .02 for what it's worth and some random thoughts that might help out...
Maybe an infrared thermometer might be useful in getting some more accurate temperatures of the stove top at various phases of the burn cycle. Here's an average one that isn't too expensive:

This might give you a truer picture on stove temps since there is some speculation in your thermometer's performance and suitability to this application.
It took awhile but I think you finally got enough info on how to fully load the stove...previously it appeared you were not putting enough wood in. Everyone has given good advice about that and maintaining a proper burn cycle where you fully load the stove and then don't open it until there's only some coals left (usually 6-10 hours later) to start another burn cycle. It seems like you are trying to implement these changes but are not getting very good burn times, hence have returned to adding more wood after a few hours. This situation might be a result of what seems like poorly seasoned wood which I think was also mentioned. Additionally, I saw in a few places where you said something like "I finally saw some secondaries" and "was able to cut the air almost down to 1/4". That might be another part of the problematic burn times...I don't think you are ever cutting down the air enough (all the way) for the stove to be burning on just secondaries which maintains the high temperature and extends the burn times. The fact that you have creosote build-up in your liner, it takes a long time to get the stove up to temp, you need a lot of air to keep the fire going and your useful burn cycle is too short all point to sub-par wood (possibly poor draft). Unless you tried this already, I believe somebody mentioned getting a load of kiln-dried or store-packaged wood or even biobricks so you can go through the process of trying to run the stove with known dry fuel. That way you can determine once and for all if your stove can maintain temperature and produce a normal burn cycle that should last longer than an hour or two.
Thank you, Slayer7, for your valued input ... and, I am still considering getting an infrared therm. I do have a positive update to share:
Today, I set out to find a new wood seller. I was seeking BETTER wood than what I had last bought. So, I took my MM with me, always asking permission of course, before I probed the two sellers wood. PRIOR to getting more wood, I was going to take off the OAK to see if this would make a difference. I ended up taking the metal band that secures the hosed insulation to the metal add-on for the air to get into the stove from outside. I got a bit nervous about such a bold move and put it back onto the back of the stove, without the tight fitting metal clamp.
I even moved the darn thermometer to the left of the stove's surface, as "E." had mentioned was where he placed his. Mine was always on the right. I know. I know. Silliness, like THAT'S gonna make a difference, right?
Anyway, the wood I selected was cut smaller than the stuff I got before and I told both of the gentlemen that I simply wanted the DRYEST wood possible. So, the man whose wood I bought from does seem to have made a very nice difference. I checked about 15 random pieces and they were all ranging between 10% and 20%, but, many between 10 and 16% MC.
The stove still had one old - from this morning - piece of burnt wood in it. In fact, it was the very last piece of the former rick I had gotten a little over a month ago? This morning, the stove's temp never reached beyond 325. I was not happy with this and knew I had to find some new wood, anyway, right away. I had this seller's "card," but I just couldn't call him simply because I didn't want half of another rick that would produce what I just encountered.
I started burning the new wood about 2:30PM. I left the OLD piece of wood going E/W, placed a new piece in front of it and built the rest of the new wood up going N/S. I used two Safe-Lites and one Kiln-Dried piece of Kindling. Eventually, it got up to 650 and I started shutting it down at 1/4 increments. I ended up playing around with the air when it reduced to 475.
Here's the exciting (to me) part: I opened the air up a bit more and within a few minutes INSTEAD of it continuing to go down - as is the normal history of this stove since it arrived - the thermometer crept up to 525.
Granted, it was the first burn with today's new wood (it's seasoned Oak, white and a little red), cut much smaller (15 and 16 inches, he said), than the other stuff I had. It's 6:15PM right now. The wood pieces are turning into ash logs and there's plenty of red in the box. The door has not been opened since 2:30PM and the stove temp is now at 425. No, it is still not at 525, but, it did stay at 525 for quite some time. Because the wood is now turning to ash, I am waiting until the temps drop to say, 325, before I will add some more of the new wood.
Now, this might not sound like much to someone else who is use to 9 or 10 hour burns, but, for me and what I've experienced; especially with a lot of bad wood I've encountered on and off since November, 2014.
I think it will go another hour, maybe 2 more at the most. The stove was almost full, but, I think I can fit maybe 3 more pieces the next time.
