I do know from simulators, on take off a 90% throttle setting saves a noticeable if little amount of fuel vs. 100% thou all take off procedures I know of call for full throttle at least initially... So whether commercial airline pilots do this is another story, airlines may have changed the procedure thou private small plane pilots (owner-operators) might.
It might save fuel but at some point one questions the integrity of the procedure, it's one thing for a private pilot to do it because of familiarity with the plane he can always give it more or less based on his own judgment... But from a commercial stand point I am not so sure if airlines would allow this.
