Show me an official Boeing document where Boeing advises against using the speedbrakes in an intermediate position... I have flown for a lot of companies, have thousands of hours on Classic and NG but NEVER, EVER have I seen, or flown with someone who doesn't use an intermediate position if needed.
What Boeing DOES recommend is something entirely different: It recommends to use caution, read: move SLOWLY, while moving the speedbrakes between idle- and flight-detent.
