Shannow, Terez has actually read the notes. While there are certainly some errors in what they put in to the companion, they are nowhere close to completely wrong. Take Cadauane. The notes actually do have her in two positions, and it is likely RJ upped her strength. So they took her final strength to be that higher strength. Some other entries that reflect her older strength were just not updated.
I know it must be crushingly disappointing that your moronic insistence that the Forsaken were more than 200% Moiraine's strength has been completely quashed. So, of course, you want to completely reject everything the Companion says. Unfortunately for you, Terez and Dom have gone through all the notes with the OP. They have pointed out the errors in the Companion, and they're nowhere close to enough to reject everything the Companion has to say.
