I've never read anything like that on the FCOM or FCTM, nor it's my company's SOP.
I believe that 2 or 3 years ago there was a Boeing audit on our flight ops department that brought a lot of changes (our NOPs had a lot of differences from the manufacturer's suggestion), but nothing like that was pointed out by them.
If this is really something recommended by Boeing for every approach (737NG), please, I would like to know where I can find it.
Great discussion guys...
