Lets say I want to go from 91 to 89 on the drum dial for the tension on my head. What is the best procedure to do this? Do I just loosen all the hook nuts to completely loose and work up from nothing again, or do I back it down slowly and evenly to 89?
Also, when loosening a head (in general) do you do it in the same way you tighten it (i.e. loosen evenly across the head) or do you just start loosening and go around in a circle?
Thanks for any input
I'm definitely a novice at this, but usually I just put my dial at every hook and back it down to wherever I want the tension, then move to the next.
Obviously, some tweaking may be required after you’ve made your round, but probably not a lot.

Loosen all nuts by half a turn, that should get you to just about at 89 and that's about all there's to it.
I use the Drum Dial to monitor a section at a time. I zero it out first. Then I place it midway of a quadrant of 6 hooks. I loosen the 6 hooks to the desired tension. I move to the next quadrant of 6 hooks until all 24 hooks are at the desired tension. When done, I remove the Drum Dial. The Drum Dial is the only known tool to live monitor head tensioning up and down.
Bart Veerman's proceduer should work, but be aware that any time you loosen the head, it will take some time for everything to settle into place. There is usually some slight sticking at all the places (tension hoop, tone ring or rim) that the head contacts.
Thanks for the responses. I am just experimenting with different head tensions and wanted to make sure I was doing it correctly.
Mr. Bart's advice is the way to go -- loosen all nuts by an equal degree of turns.
Loosening one nut can affect the Drum Dial reading on other nuts -- to get "tension" on an object, the object has to be tied to two ends. That's why the equal turns work well.
After loosening all, then just barely nudge the nuts clockwise to take the lash out of the threads. Barely nudge, by the smallest amount, less than 1/64 turn.
Once done with that, come back the next day and recheck for even tension, tweak as needed.
