Fun story.
I used to run about 30-35ft/lbs barrel torque, in the range where you could use your feet to hold the butt stock and a clamp on barrel vise to pop the barrel off without putting it into a fixture. Never had any issues with accuracy or otherwise.
One day I adjusted my muzzle brake with a crescent wrench, loosened and tightened it a couple times to get it lined up correctly. Then later that week I shot a one-day PRS club match. I won the club match, cleaning the last stage, tossed my rifle in the bag and drove home.
When I got home to clean the gun I looked and the muzzle brake was crooked. I thought...
Well darn, I tightened that. How did it come loose? I reach to grab the muzzle brake and it turns out the brake was tight but the
whole darn barrel was loose.
Now I run about 75 fl/lb.
