Not sure if we are looking at the same things. Here is a table from that presentation:

Standard Body Airplane

CFM56-7B26

Average 5% reduction from full thrust
$/Year/Engine

22,000 - 26,000

Average 10% reduction from full thrust
$/Year/Engine

40,000–49,000

Average 15% reduction from full thrust
$/Year/Engine

55,000–68,000

Average 20% reduction from full thrust
$/Year/Engine

69,000–84,000

There is no flattening to be noticed in this table. Slide 9 shows a start of some flattening at around 40% reduced thrust. Please note these are maintenance cost reductions.
