Manometer Placement and Reading

Would a manometer reading be greater above the fire or under the grates, or would they be the same?

Since I have an internal damper I can't get a reading above the fire before the damper so I was wondering how my values compare to what is discussed on here. I have been sticking a metal tube connected to the manometer thru the air intake slots for my reading. My draft never goes lower than 0.07 even when the temp is in the high 50's and the stove is running at 200.

Next year I will try to somehow put a baro in the flue so that's why I was wondering about the values above and below the fire.

The critical place is above the fire. the flue pipe is the convenient place.

I found that the draft is .005 stronger under the grates than over the coal bed.

Just to elaborate on that, I've done measurements everywhere.. Even considered seeing if my sphincter had a measurement.. Butt not.. Anyways, I found that the pressure is nearly equal everywhere. I measured below and above the coal bed and also before and after the barometric damper. I found that under the grates was .005 stronger than above the barometric damper. I think that the draft pressure under the grates is a hair stronger because the coal bed creates a tiny amount of its own draft. Air going up thru it, gets heated and gets lighter. Towards the end of a burn cycle that could change as ash collects on the grate restricting air flow.

The only time I saw a huge difference was before and after a manual damper, which seems obvious since it restricts air flow.
