Working with banjos for many years, I have tried all the gadgets out there to set up banjos. To tighten a head, keep the hoop even all the way around as you tighten, and tighten each hook 1/8 turn at a time.
Once the head feels fairly tight when you push on the head, then play the banjo with the resonator on until it sounds good to you, tightening a little as you go. IF YOU USE A TORQUE WRENCH MAKE SURE THE HOOP IS EVEN AS YOU TIGHTEN AND TORQUE TO ABOUT 12 ON THE DIAL AND YOU WILL BE CLOSE. A DRUM DIAL SET AT 90 ALL AROUND WILL BE CLOSER TO TO WHAT YOU WANT. TORQUE WRENCHES VARY DEPENDING ON THE CONDITION OF THE HOOKS.
