Fuel Burn: Max power vs. Reduced Power
Could someone please explain the reasoning behind the fuel burn differences from using max power takeoff/climb thrust to using a reduced power takeoff/climb thrust. I understand that the max power uses less fuel but I cannot find a reference for an explanation. I know this has been explained before in the past on here but I have spents hours searching on Google and the archives on pprune but have yet to find a good explanation, thanks a bunch!

The higher the pressure and temperature inside a turbojet engine, the more efficient it gets. You get higher temps and pressures by pushing the throttle forward more.

My understanding is that simply getting to efficient cruising altitudes quicker - by using full clb thr, saves the fuel.
Reduced T/O and Clb thrusts are for engine costs/life not fuel economy.
