Very good point...
I'll normally do a minimum of 4 rounds of tightening the tension bolts.
1st @ 10 lb-ft
2nd @ 20 lb-ft
3rd @ 30 lb-ft
The above is done with the Mazda recommended torque pattern in the FSM.
I'll do one last torque down set at the same 30 lb-ft final but just go around in a clockwise pattern - that's #4.

I may do a little experiment. I may buy both a cheap Harbor Freight clicker as well as a Craftsman. I've got some spare trashed n/a irons. I may find a spot to tighten a bolt down with all 3 wrenches and see how much variance there is. Maybe just do a nut on an exhaust stud?

Good idea but stay away from the exhaust fasteners.
Most dedicated exhaust fasteners have special (thread) profiles to keep them snug - usually the female or nut side of things.
Torquing and retorquing might not be consistent.
I'll try and pick something else?
