I wouldn't blame a strong draft for the clinkering. Clinkering occurs mainly with red ash coal. White ash coal clinkering usually only happens when running her really hot. What I'm trying to say is, its not a strong draft pressure that causes clinkers, its the volume of primary air. Where you pushing the limits of the stove? What color ash does your coal produce?
Anyways, I'm a baro guy.. I think a steady draft pressure makes for the most efficient and predictable burn. Anywhere between a -.03 and -.05 seems to be optimal for most hand fed coal appliances.
After a fresh load, open the MPD till it gets burning good. Then close it till the Mano drops to a -.05 with the primary set for a normal burn heat output.. It should settle down a bit after the chimney flue gases cool some. After that, you may need to open the MPD a hair so the mano doesn't run low. "It depends"..
A MPD is really sensitive to your chimney's specific drawing characteristics where a baro will automatically adjust to it, usually.
