Boeing don't define "considerably less."
Well, Boeing doesn't define the N1 as that is demand scheduled and can actually reach full G/A thrust if required. It is scheduled to give between 1000 and 2000 fpm climb rate, with an aim to reach 1500 in an ideal case. That is availalbe whenever the AT system is active, for those airlines (like the one i'm working for) that use the ARM mode it is available in manual flight as well, thus precluding any requirement to figure out any thrust demand for oneself. However it ain't hard to do it manually if needed, just aim for around 1500fpm fly the aircraft.
