Dexter bearing adjustment procedure

I totally get NOT using the EZlube fitting (ruined some brakes), Timken parts, and annual service. What I don't get is the conflicting methods being used to set the zero backlash on the bearing, i.e., 0.001 to 0.005 clearance.

My previous trailer had Alko axles, and I adjusted the bearing per Alko recommendations: rotate and tighten to 20 ft-lbs, loosen nut without motion, tighten to 8 ft lbs, back off one castellation, stick the pin in. Never had a problem in 60,000 miles.

My 2018 Rockwood has Dexter axles. Dexter says to rotate and tighten to 50 ft-lbs, loosen the nut, and then "hand tighten" the nut and back off a bit. What kind of procedure is that? Hand tighten?

If you go on Youtube, people are doing all sorts of crazy stuff, everything from tighten by hand and back off a full quarter rotation.

The Alko method seems scientific, the Dexter method seems weird, and many of the Youtube ideas will cause a failure I'm sure.

So .... from someone who has actually done this several times, and has gone 10's of thousands of miles ... how are you doing it?

PS: Dexter didn't see fit to install brake adjustment hole dust plugs which causes me concern for their commitment to quality.
