well, I said it's an over-simplified example
somone with 300 CP can spend 50 each of their thief points on magicka regen and magicka cost reduction. for ~15% and ~10% bonus respectively
somone with 600 CP can spend 100 points each on that same stars, resulting in 25% and 16% benefit, plus unlocking additional passives.
Overal, this means the 600 CP player gets about 80% additional power out of the system compared to the 300 CP player. yes, 80% (varies depending on the actual passives unlocked from the respective tree, and the precise diminishing return curve) more power for 100% more investment IS diminishing returns... however, it's barely diminishing.

Your first points will provide you the largest benefit of abilities as well as the most useful abilities, the most useful perks, as well as stat points.
Later points will provide less useful abilities and less useful perks as well as stat points
Beyond that you will get no perks, and even less useful abilties and stat points.
The final points provide no perks, no stats points and the least useful abilities.
The overall effect of the champion system is in fact rapidly diminishing beyond the 600 CP mark or so.
