Also whilst we're on the subject Boeing FTM says select idle reverse on main gear touchdown and the rest (detent 2 or max) when the nose gear touches.
I see some pilots selecting reverse thrust much too late! Also if you're using a/b 3 or MAX by the time you've thought about it the nose gear is on the ground so it's best to think of it as one continuous selection.
Am all for economy and reduction of noise etc. but Boeing put Flaps 40, autobrake (backed up by manual brakes) and reverse thrust on the a/c for a reason - if you need it use it!
