B744/8 manual takeoff thrust setting (GE)

With autothrottle inop, does anyone have a detailed procedure of how to accomplish setting takeoff thrust for the B744/-8?

I assumed it was just:
PF spools all 4 evenly to 70/45% depending on variant
PF advances thrust to approximate calculated N1 and states “set takeoff thrust”
PM adjust thrust to within ~1% of target by 80 knots.
If FO is PM, they adjust thrust from lower part of thrust levers while CA/PF keeps hands on top in case of reject.

Apparently some pilots interpret the Boeing FCOM to mean that only the PM can advance the thrust past 45/70% and that the PF isn’t supposed to set them close to target takeoff N1 on their own.
