Yeah Cal, post the chart, you don't have to translate it, it's impressive folks!
I burn lump charcoal in my smoker and not wood, but there are pieces 1-2 inches (2.5-5cm) to 5-6 inches (12-15cm) and the only time my temps rise are when I open my vents, as Dan said he uses large pieces of wood and he can maintain a constant temperature with them.
On you chart you show your vents to be either open or closed, but nothing in between, try starting your fire with the door that the vent is on open and when the fire is burning close it and then try closing the vent 25%, wait a few minutes and see what temp you have, continue this until you have a steady temp from using the vent to regulate the intake air, also when you close all of the doors if they are leaking smoke then use some aluminum foil (papier alu) to seal them, this way all combustion air is entering through the vent. Once you can maintain a constant temp, preferably around smoking temps, if it is too high that is ok, just close the vent 5-10% and watch the temp lower, do this until your are at 225°-250°, record what the vent position is and then next time you can catch the temp when it is rising, that is, start the fire with the vent door open, the vent set at the correct opening and once the fire is going close the vent door and watch the temp settle in at your smoking temps.
