Leanne says they're not even one third of their original strength. And I don't know where you decided to put Kairen in the same range as Temaile. Kairen is strong, though somewhat weaker than Anaiya, according to NS.
Leane makes this statement:
Leane shook her head. "No one has ever been Healed from stilling before. Maybe the others will see it, say like being wilders. That puts you a little lower than your strength. Maybe having been weaker will count something. If Nynaeve couldn’t Heal us all the way the first time, maybe she’ll only take us to two-thirds what we were, or half. Even that would be better than now; but still most here would be as strong, and a good many stronger." Elayne stared, more confused than before. Nynaeve looked as if she had been hit between the eyes.
It's clear that they are less than half of their former strength, but there is no statement that they are less than 1/3 of their original. If anything it seems like they are between 1/3 and 1/2 of their previous level.
Kairen is weaker than Merana as we see when she is tasked with taking the TR girls to Salidar.
