We know Cadsuane is not stronger than the wonder girls for example.

And the actual absolute strength comparisons between different people on what is supposed to be a linearly distributed list (yeah right), make no sense whatsoever compared to what was presented in the novels.

In short, "Team Jordan" had no clue what was going on in Jordan's mind as far as the One Power is concerned.

EDIT

Also, regarding Taim's strength, there was no need to provide it, because Terez has revealed that in Jordan's actual notes in the library, it is revealed that he lied to us all, seeing as Taim was actually Demandred, at least up to the end of Lord of Chaos.

Yeah, I know, shocking, but true nonetheless.
