Thought I would respond to this as I run the gamut of weather conditions, wood types, etc.
When it is like 10 degrees or colder outside, given the nature of this house and my stove type (see sig below), I will load splits in north-south so my air flow from my front loading stove goes with the splits. Faster burn times of course. I can get approx 6-7 hours on a full load this way.
Above 10 degrees, I will load east-west.
Depending on the wood, and the temperature conditions, I will vary how I load and what I load. For instance, if I am in that 10-30 dgrees outside range, I may load oak and/or pinon, east-west. This way the air flow is slowed and I get longer, even burns. I have to close everything for all intents, down, though there is still a minimal air flow occurring and things will work well. If I am burning pinon or cedar, or all oak, these can tend to produce wonderfully high heat even when things are dampered all the way down. If things are too fast, the draft is going too well, the wood is just too perfect, or if things are warmer than say 30 degrees, and I run the risk of overfiring, I have techniques where I will place different kinds of wood along different layers. I can maintain three "zones" of splits in my firebox, perhaps two, sometimes three splits high. What I might do is place a high heat split in front. In the middle I may put some moderate wood, like elm or mebbe some not quite perfectly seasoned oak pr pine, or I may place in a full round in my middle layer. Then I may place a high heat puppy on the bottom of my last layer near the back of the stove, with another one or two moderate type wood splits on top. I end up with being able to control the speed and flow, and for all intents, heat of a load over the course of 6-10 hours, but the types of wood at each layer. Sometimes I will place a high heat split along the bottom of all three zones, and then a full round on top of each one. Gets things coaled up on the bottom, which then move more slowly through the unsplit round on top. All this loading east-west, and I can get easily 10 hours or more on this stove which is a modest stove design, nothing fancy. But it works for this house and environment. If it were colder here, I would have opted for a more efficient CAT stove. But I've been able to use this layering technique to manage slow to fast burns. But in a pinch, I go north-south with say, pinon, and can get the joint warmed up fairly quickly. East-west, north-south, layering the types of wood depending on the conditions. Have been fairly successful in keeping the digs cozy even at during extended subzero times. And when things go into the 40s or 50s, I have these wonderful coals which will keep things comfy all day.

I will have to check it in the AM when the fire is down and out as I highly doubt I will get even close to an all night burn at this rate (don't get me wrong...I am very happy with the unit). I have a dynomite draw from the second I strike a match. Ironcially though it is an exterior chimney but it is a very heavy chimney with ext. brick, 8" CMU and then clay liner. 22ft high. I used T316 flex liner with no insulation. I'm thinking there could be a decent chance that I did not solidly close the ash tray cover. I'll report back in the morning. The small hole you are talkign about is right were the action is but it seems like too much air for what you describe unless my draft is that off the chart which I doubt. I'll get to the bottom of it tomorrow.
All that said, my upstairs is 78 degrees tonight and we are LOVING it!
