This PROVES you WRONG !

"We have received a report of two occurrences of engine thrust rollback
(reduction) during takeoff on Boeing Model 777-300ER series airplanes powered
by GE Model GE90-115B engines.

Investigation indicates that these events are the results of a software
algorithm in the FADEC that was introduced in software version A.0.4.5
(GE90-100 Service Bulletin 73.0021). "
