Default Torque Converter Break In

So Yank converters say they have a special clutch lining material that requires a special break in procedure. This procedure consists of, Driving the converter at normal speed with NO WOT starts or brake stalling the converter for approximately 150 miles. Stall checking or Brake stalling will severely damage the clutch lining if converter is not broken in properly. Should i stick to these procedures? Its 3600 Stall...

I have never understood break in on a converter , But advise doing what the manufacturer says .
Now on a trans that is new I suggest driving normally for a 50 miles or so then let sit overnight and start warm top off and do as you will. But the only point in that for me is to get foam and air out common with first start up and run.

On first start up to bleed the air and such out, I will manually run down the gears PRND321 and back up 3-4 times sitting and idling. Checking fluid and topping off each time. Once the oil doesnt go down, road test it is. I also ensure my dipstick (whether factory or aftermarket) is reading correctly before any fluid gets dumped in.

I never understood how breaking in the TCC clutch is affected by WOT. The TCC clutch will never be applied at WOT or when brake stalling the converter, unless the tune has been changed to allow TCC apply at WOT. So how does this effect break in, but these things aren't cheap, so I always tried to do as instructed?
