Had to redo the same torque check 3 times before I caught the pattern

I spent about 6 months torquing wheel bolts on 737 main gear the same way my trainer showed me. Tighten in sequence, go around twice, done. Then a senior mechanic watched me one day and pointed out I was pulling my wrench too fast on the last pass. He said I was basically clicking past the real torque value on the final bolts because of momentum. He made me slow down and do it at a steady hand speed and the difference on the dial was like 15 foot-pounds. Felt pretty dumb but now I check my cadence on every torque job. Anybody else had a simple habit that was throwing off their readings without realizing it?

Slowing down my hand speed fixed the same exact issue on my torque wrench at work.

So did you actually dial it down on purpose or just naturally slow your roll one day?
