Clarence,

All variables are defined. I suggest you think again.
Here is DAL's question;

My main example would be CF6-50C2B (53,200lbs).
Does the engine achieve this thrust at 100% N1, or does
it achieve this power at the maximum N1 setting, between 117 and 118.5%?


The thrust (53,200 lbs) is the PUBLISHED thrust by the FAA.
Now the FAA publishes their thrust as MAX TO THRUST at ISA
(Standard Athmosphere which is Sealevel, 15 deg C, 1013,25 mb)
If you look that up in your diagram you get about 111,8 N1 - PERIOD!

barit1 gives an excellent explenation, but it's not answering the
question above.

There is probably other scenarios where you will get exactly 53,200 lbs of thrust, but thats not the point here.
